K-SWISS Men's Ultrascendor Tennis Shoe

I have worn this shoe in the past and thought it was discontinued. Whatever, it looks like its now available and I snapped up a pair hoping to relive yesteryear's fit and the shoe did not disappoint -- I will say that the toe box is a little snug compared to what I remember. Great high arch support -- better than any shoe that I have tried recently, and I have tried a few trust me. I am happy with them and wish that they would bring back the same shoe with the higher ankle support. This should be a good market for that type of shoe especially given the growth of senior sports and athletics.

On my 26th pair over the years. I have played five day tennis tournaments with this shoe right out of the box and have never been uncomfortable. No blisters, no hot spots, just plain comfort. Consistently great materials and workmanship over the years. This shoe has been in production for some time now. My only criticism is that the tread wears out way before the upper parts. Expect a little below average wear index on tread. Exceptional comfort and traction on wet courts. This shoe does tend to favor the wider foot.

With an arthritic knee nearing 70 years of age, I am fussy about my shoes. The K-Swiss Defier and Ultraschendor have served me well. For tennis, they are my favorite. When my knee starts hurting, I know it is time to get a new pair, which I do 2 or three times per year, even though they still look good. Different folks find different shoes to be a good fit, so perhaps there are those who will not find them to be as comfortable and supportive as I do, but I am very satisfied.

Bought these based on some reviews that claimed this shoe to be a close replacement for the NB804/6, not even close as far as my fit is concerned. Yes I am one of those also disappointed with what the other company did with my favorite shoe and am looking for a replacement. 1st off, K-Swiss does not seem to make different widths so if you have very wide feet, you are out of luck. Major differences are the Ultrascendor has a much higher arch and only offers a normal width (narrower) toe area, the heel height is higher from the ground and there is less ankle clearance - meaning the foot sits deeper in the shoe or the sides come up further towards the ankle. So overall, this is quite a different fitting and feeling shoe from the NB804/6 series, and I would not call this an equivalent alternate. However, by no means is it bad shoe, it is just quite different. Now the good part: it is a stiffer shoe that does provide additional stability over the NB804/6 series even though it places the heel higher up off the ground. The grip vs wear also seems to favor longer lasting wear though grip on the hard courts that I play on has never been an issue. The shoe does feel bulkier with more padding in the uppers and the heel cup can rub the back of the achilles slightly. I do not feel that the heel reinforcement is as strong as the NB804/6 series since it does not have that hard heel cup, so I would suggest not to slip on the shoes without undoing the laces first as this one is easier to collapse. It took me about 90 minutes to adjust to this shoe before it faded into the background and I no longer thought about it. So from a replacement point of view, it is not a direct replacement for the NB804/6, but I would re-order this shoe in a 1/2 size larger next time. Construction and quality wise, it is as good as the NB804/6, the lower price seals the deal. I've been converted.

I really wanted the exact same shoe in the mid version as I like the extra ankle support but could not find it anywhere on the web. This shoe fits perfectly and has the same long wearing soles as the mid so if my ankles get sore I'll just wear an ankle brace with the shoe. K-Swiss has a winner with this and the mid shoe. Hope they never discontinue them.

So glad that K-Swiss continues to make this shoe ... and very glad that it was being offered at a reasonable price. For me, this is the Pirelli tire of tennis shoes and they have saved my footing more than once! Great materials ... solid footbed .... comfortable on and off the court ... and the traction!! I've worn through a half a dozen pair over the years and that takes some real effort! allen

These shoes are the best for tennis they are very sturdy & with an orthotic support the my feet better than any other make

had Ultrascendor back when they came out and these are my 2nd pair... love 'em ... the fit; the style; the durability ... top notch
