"...skied all day without my usual knee pain.  I also skied with a lot of speed with confidence and good form.  CADS seemed to enable me to be in proper ski position and use my edges without pain."—R.Z., via email

"We just wanted to let you know how happy we are with our new CADS. They have really improved our skiing, particularly over bumps, and no leg pain!"—R. & J. O., via email

"Thanks for keeping my knees happy suring ski season."—A.S., Enfield, NH

"It was dramatic how much the CADS helped release the pain.  I could ski all day!"—P.B., after demo

"It worked great!  Literally NO pain!  Skied 5 days straight.  I haven't been able to do that in years!"—R.C., vis email

"...my knees have not felt this good both on and off the snow in some time.  Where I was getting some residula pain/discomfort prior to [CADS], I now have almost no lingering discomfort...with less than ten days under my belt I am in a very good place, especially considering I expected to have abandoned the season if no relief was in sight.  At the point I don't elieve a synvisc shot is even necessary.  I cannot thank you enough for creating such a wonderful 'contraption.' "—A.P., via email

"Thanks a lot for your help; you saved my vacation.  Without CADS I don't know how I could ski so much."—G.R., Mexico

"I just wanted to tell you that the CADS were a big hit with [my husband].  He said that he could really feel it taking pressure off of his knees at times when they would be "screaming."  Thank you for all of your help in getting him set-up in Steamboat."—S.J., via email

"I LOVE CADS! It is the difference between groomers and double blacks.  Thank you, thank you, thank you!  Keep it up."—C.C., Hampton, VA

"Many, many thanks for giving me the opportunity to try, and then buy (!), the CADS system this past week.  My family has a history of bad knees, and alothough I have no problems yet, I think my CADS will go a long way to ensuring skiing does not break my knees down.   However, that is not the main reason I am so excited about having my CADS.  Being able to now ski ALL day, versus 2-3 hours before my legs gave out, has again made me really excited and anxious to ki again.  As much as I love skiing, I never have the opportunity to get out frequently enough or exercise enough to make me a "machine" when I do hit the slopes.  Your product has enabled me to again enjoy the greatest winter sport like I did when I was a kid."—M.M., via email

"I had 18 knee surgeries in the past.  The last two were total knee replacements.  I am 61 years young and in very good shape despite the trauma I have had in the past.  Last year I was skiing at Park City with my CADS system.  I tore the alligator clip when dismounting from the chair lift.  I could not ski down this long run to the bottom with only one rod, so I just tied the cords around my waist and skied to the bottom.  Prior to this incident, I was feeling good and skiing with very little pain.  

That changed quickly as I soon learned how much help the CADS system provided.  By the time I reached the bottom, my knees were aching, my thighs were sore, and I generally felt like crap.  I improvised by attaching my cord to my boot with a plastic tie wrap normally used for attaching lift tickets.

With my CADS system in place, I was able to ski the rest of the day and the rest of the week without any of the aches and pains of skiing sans CADS.

I am a firm believer in the value of CADS and can ski relatively pain free with them."—G.T., via email 

"Had a great day on Monday with my CADS!!.. my friends could not believe how long I could ski and that my speed was way up!!.. You da man!!...Every skier with sore knees should own a pair of CADS just like they own their skis and boots.. Mandatory equipment for us baby boomers!!"—G.E., via email


"My CADS have literally saved my skiing.  Having had multiple knee injuries and surgeries, my ski days were rapidly coming to a painful end before I learned about CADS.  Prior to CADS, my pain level was increasing and my ability to ski bumps and powder was seriously decreasing.  I still have some pain, but with CADS, I'm back skiing the bumps and powder and postponing knee replacement.  Besides the relief I've gotten from my CADS, the service that you guys provide is terrific—always personal and always prompt.  Thanks so much for saving my skiing."—T.O., via email

"After seven days of skiing, I proclaim my CADS are superb!  The joy of skiing with CADS is exceeded only by the pleasure of knowing both of you!  ...Prior to CADS, I was spent after ten or so runs inspite of frequent stops.  With CADS, I'm up to 18-20 per day—non-stop!  Thank you for doubling my skiing pleasure!"—R.H., Rancho Mirage, CA

"I was skiing at Beaver Creek when I spotted a women skiing with CADS.  I asked her about  them and she waxed eloquently with joy.  With no cartilage in either knee following two surgeries from various athletic injuries on both knees, at the end of a day of skiing I am in excruciating pain, but my wife loves to ski and I will not leave her.  I ordered the CADS the very next day and will never slide down a  mountain again without them.  they were easy to put on, effortless to ski with after 3 test runs to get the feel for the new weight of my boots in my skis now that a great deal of my body weight was traveling directly to my boots and bypassing my knees.  I skied like I was floating on air and never wanted to leave the hill after 7 hours of non stop skiing.  My wife is thrilled that she no longer need worry about losing her favorite skiing partner.  CADS are a true miracle for any skier with tender knees and likely will save many a knee from the deterioration of age if one is smart enough to begin using them before a problem  arises."—Jay Lehr, Ostrander, Ohio  740-368-9393

"I purchased my CADS three seasons ago and this year I really put them to the test.  I had surgery on my knee four months ago and it was not successful.  Then, I was laid up for weeks with a blood clot in my leg.  My knee still hurts to walk, especially up and down the steps.  However, last week, December 28 - January 5, my family and I went skiing.  I skied all week with no pain, thanks to my CADS.  I turn 65 next month and I'm looking forward to many more great years of skiing.  Even though my grandson calls me Mrs. Gump, I can still beat him down the mountain!!  The CADS have truly enabled me to continue skiing.  Thank you!"—V.S., via email

"I'm a ski instructor with Multiple Sclerosis, and over the years I've taught thousands of children to ski.  My 3 year old son has recently expressed interest in skiing, and before I got my CADS there was no way I was ever going to have the strength to teach him.  Walter, thank you for making it possible for me to pass on my love of skiing to my own little boy!

 To anyone who has MS, don't give up skiing before you spend a day with Walter; you'll discover what I have - that CADS really work!"—R.K., via email

"...they were fantastic! During the previous year I could only ski for 2 days then had a day off to let my knee recover - last year with CADS I skied 6 consecutive days.  And it did not take long to get used to them. What I did find is that they forced me to ski 'properly' i.e. edging / carving the turns more and deliberate unweighting instead of lazily skidding the skis around. Net result is I just skied faster.  So well done for an incredible invention." —P.W., via email

"For ten days I have been on the look out to see you on Vail Mountain, to say thank you for the joy you have provided in a couple of years of pain-free skiing that would otherwise have hurt so much I would have given up skiing... thank you, Wonderful invention. Well done."—M.S., via email

"...I also cannot thank you enough for the CADS system. Without that , I wouldn't be able to enjoy the mountains at all. I just wish everybody who needs it, could become aware that there is something as wonderful to assist them. Just happy that we went to Vail to come across it and that I can benefit."—A.O., via email

"...I skied more this past week then I have in years.  I skied for 5 days straight for at least 5 to 6 hours per day. I can't believe it! Before the CADS I could only ski about 2 to 3 hours every other day. I skied extremely steep terrain at Squaw Valley and knee deep powder at Alpine Meadows with no problem at all. For the first time in many years I wasn't the person suggesting we end the day. Thank you for giving me my "ski life" back!!"—M.H., via email

"Thanks for taking the time to convince me to try your CADS system.   I ski for a living, demoing new skis I invented [see www.racingblades.com], skiing steep bumps almost every day.  My leg muscles are rock hard and almost never fatigue.  However, my knees get worse and weaker and more painful each day until I need to take almost three days off from sking  Even walking and stairs after skiing are a real painful task.   Now, after skiing your CADS system for a week straight, my knees have no pain.  They seem to have healed and strengthened.  This is just what I needed.  Not knee surgery!"—A.F., via email

"I can ski all day, top to bottom with little stress or additional pain in my fake knees.  It was fate that we met on the chair.  I'm a "born again" skier.  THANKS!"—H.O., via email

"...I would have been lost without the CADS on this trip.  My knee would never have held up on its own.  And, I must admit that the CADS improve my skiing because I can't get in the back seat—i.e., it keeps me forward on the skis...I feel that if only people would give these unfashionably efficient CADS a shot, they too would realize their marvelous ability to take the bumps out.  My legs were not nearly as in shape as previous years and I had virtually no thigh burn or knee swelling."—A.S.W., via email

"Skied 6 days straight on knees that [had been] signaling me to quit skiing. Did 6-7 inches of powder in back bowls like an expert better than I ever have in my life.  Boogied Blue Ox all the way.  Did the bumps on Zot with style and ้lan.  All this quite hard to believe that in December I was considering leaving the sport.  I am a Born Again Skier!  I cannot understand that anyone with bad knees doesn't beat down your door in search of a fitting.  I realize that this high praise may seem a little beyond, but it is all true."—S.R., via email

"CADS have given my wife the ability to ski all day long!   Before we got the CADS she could only ski 2 runs a day, now she goes all day without a break!  Her skiing has also improved tremendously--she now out-skis me!"—J.C., via email

"The CADS system has been great for my skiing knees.  I don't think that I could ski without them."—B.R., Meadville, PA

"...Then I discovered CADS. Now I can ski 5 days/week and I am not bushed at night... "—M.E.R., Breckenridge, CO

"...they permit me to ski comfortably in spite of my arthritic knee.  This permits me to ski joyfully with my grandchildren—a joy which I might prematurely have to forego if it weren't for CADS."—J.B., Manchester, MA

"... it enables me to ski more difficult terrain with less exertion of my quadricep muscles and without placing stress on my knee joint."—J.S.R., DMD, Greenfield, MA

"...your development of the CADS system has been one of the most significant contributions to ski technology in my twenty-two years of skiing.  Skiing thirty to forty days a year, trying every new development, only CADS really impacted my life as a skier, by significantly extending both the duration and level of my skiing.   At sixty-one, I am still able to ski aggressively with much younger skiers, in spite of arthritis, damaged knees and all of the limitations of aging.  While many of my contemporaries have stopped skiing as they age, the ones on CADS are still active."—J.R.K., Palm Beach FL

"Skiing with CADS is a joy that has brought back smiles and joie de vivre to my skiing.  It is only necessary to neglect their use and bring smiles to the Marquis de Sade on skis."—B.McD., University Park, IL

"In the last few years my wife has developed arthritis in one of her knees and I have lost some of my stamina (especially in my thighs). We both found we could ski longer and, (I think) safer with our CADS."—C.E.S., Santa Fe, NM

"We are like kids again, at the ages of 52 and 60.  With CADS one does not have to head to the hot tub at the end of the day, armed with two Tylenols, and then collapse in a heap.  CADS leaves energy for other possible activities...they work just as well on our Eastern Ski Area "concrete," as well as in fluffy powder.  They help you adapt from hard packed, to loose snow.  They are fantastic."—C.&D.B., Montreal, Canada

"My family couldn’t believe the improvement in my skiing, particularly with respect to speed and stamina. ...There is no way I would contemplate skiing again without my CADS system."—N.S.H., New York, NY

"...CADS makes skiing so much easier and lot more fun; this becomes very important to a man of my age—65.  I have also found I can ski longer and without getting tired and sore muscles...I do enjoy skiing even more today because of CADS."—B.A., Tarzana, CA

"Your CADS have kept this skier, who was almost ready to throw in the towel two years ago, on the hill rather than over it."—D.S.P., MD, Grand Junction, CO

"Being back in Switzerland I became familiarized with the gear soon. Now, I am happy, as it helps me, despite my knee trouble, to ski again."—R.S., Schweiz, Switzerland

"Yesterday I tried out my CADS system for the first time, I was not optimistic.  I have had surgery twice on one knee and once on the other and after about 55 years on skis I believed my skiing days were over.  The results were absolutely fantastic.  Your Magic is better than mine.  It was absolutely wonderful to ski without pain and I am now looking forward to another ten ski seasons.   Many thanks for your revolutionary contribution to skiing."—B.D.B., "The Man with the Magic Touch," Cypress, CA

"I was hit by an out-of-control skier in 1990. My right ACL is torn and the other damage to the knee is such that osteoarthritis has taken over. Skiing with a brace gives me stability, but is quite painful...As far as I am concerned, the learning curve is short and not complicated, and the results for those with bad knees are well worth it. I deliberately have taught lessons with and without CADS, and my injured knee become quite painful after an hour-and-a-half. Later, I get swelling and aching. Almost none of this happens when I use CADS. I am skiing and teaching comfortably, and am quite convinced that I would not be able to teach without CADS."—W.M., West Hartford, CT

"Yesterday I tried out my CADS System for the first time, I was not optimistic. I have had surgery twice on one knee and once on the other and after about 55 years on skis I believed my skiing days were over. The results were absolutely fantastic. Your Magic is better than mine.

"It felt like skiing did twenty years ago. They do help. And my knees, knee caps, are worn out. I can ski, but it always gets painful—especially on the steep or in bumps. It is worth looking at, for there is a large population of older skiers, and younger ones who have injured themselves, who could benefit from CADS."—B.L., Salt Lake City, UT

"Ski season is over now, but I never fly through the powder but that I think of you and your genius. I can't even begin to express how much I enjoyed this past season because you made it possible for me to still be on the slopes...I just wanted to say thanks again for your marvelous invention. I certainly will thank heaven for the rest of my days for you."—J.T., Hamilton, MT

"I've got MS which significantly weakens my legs, though I can still walk.  That, together with MS fatigue means that I'd be lucky to manage more than perhaps 100 yards on skis in a single day.  With CADS I was skiing with enthusiasm and quite comfortably managing six or more runs a day."—B.W., London, U.K.
