    I have really liked this shoe. I do jazzercise aerobics and these have been perfect for that. I have owned 3 or 4 pairs of Rykas and these are by far my favorite.

    Of course, ZAPPOS'S service cannot be beat. Received the shoes quickly. I love RYKA and bought this particular type because I read other reviews about the wide box and not experiencing the numbing foot/toes on the elliptical. The numbing still occurs; however, not with the same intensity. I think if I had bought 1/2 bigger it may not happen. I recently started doing more high intensity, high impact workouts and these shoes, in my opinion, do not have enough forefoot cushioning for those types of workouts. Now I'm searching again.....

    As usual, the delivery of the shoes was excellent. The shoes were a gift for my daughter. We could not find them anywhere else in her size. She loves them and I very much appreciate your prompt service.

    I am really loving this shoe. I bought one pair and am considering buying a second pair in the other color. I have had many foot problems in the last few years (plantar fasciitis and an injury) and after wearing these all day, my feet feel wonderful. I only wish I could put them on with dress pants and wear them to work. The heel area feels especially nice and snug, while the toe box is large and comfy. Re: the sizing, I did have to get a pair a half size larger than I have ever bought before, to get the right fit.

    Just like other reviewers said, this shoe is a bit small. It is amazingly comfy right out of the box! This is another great shoe from Ryka.

    The sneakers have been a very good recommendation by your staff member for my problem feet! By far the most comfortable ones I have owned to date. Thanks to Ryka who knows how to make a quality sneaker for women!

    I love these shoes. I just bought a 2nd pair of the same ones. The purple is very pretty & feminine without being too overdone.

    I just received these and they are awesome. I bought the purple/grey ones and there is even detail in the purple color, very cute. Ryka is the best, as far as I'm concerned, this is the only shoe I wear for work (I'm a nurse). I have long hours on my feet and a lot of walking and Ryka is the only shoe that makes my feet feel good. They are comfortable, great arch support, lots of wiggle room in the toes and there is no breaking in period. They are also lightweight. This was the first time I bought from Zappos and I am extremely happy. I ordered the shoes on a Tuesday evening and they had free shipping and I received the shoes on Thursday afternoon, less than 48 hours for Internet shopping. Wow!

    I am surprised a what a great shoe these turned out to be. I was willing to pay up to about twice what I paid for these! I really only wanted one thing, comfort and good support. These shoes fit my inserts perfectly and have a high enough back on the heel so your foot doesn't slide out when inserts are put in. The other great thing is the wider toe box. I always used New Balance because of that and have not had good luck with the last two kinds of NBs that I bought. I stand on my feet all day so when I work out it is essential that my feet are in a very good shoe due to the extra stress on my arches and feet. I love these shoes and the price makes them twice as nice. They also look nice on top of everything else. I will be buying them again.

    I have had Rykas in the past so I knew of their fit and comfort. I love this shoe! It's a nice snug fit around my ankles and is as true-to-size as I've ever found. I do a lot of gym activity, from kick boxing, step, high aerobics to spin and this shoe gives the perfect support for me.

    I bought these based upon the recommendation of my exercise instructor and am happy with them 100%. She advised me that Ryka tends to run a little small and suggested I order a larger size; I did take a larger size in a similar Ryka shoe, but was my usual size for this particular shoe which is the one I kept. It is flexible and comfortable with the right amount of padding and support for my cardio and strength classes. I will buy more of this brand!

    The shoes are wonderful. I followed the advice in other reviews and ordered 1/2 size larger. They fit perfectly and are so very comfortable - no break in required.

    Great workout sneakers - I purchased these sneakers after wearing Asics for almost a year and loving them (but couldn't find another pair that had the same results). I thought I would give Rykas a try. Love these sneakers; very lightweight. Had to order a whole size up, though. I like toe room. I also ordered the mid height in black and the studio flex went up a half a size in those. I do cardio kickboxing weight training and these shoes are excellent. I think Rykas are my new workout shoe. And with Zappos return policy and free shipping both ways you can't lose.

    These are very comfortable shoes from the very first day that you wear them. I like that they are synthetic because I'm a vegetarian that does not wear animal skins. I like them so much that I bought two pairs, one in blue and one in purple.

    I bought these shoes last year to replace a pair of Adidas shoes that were ripping up my ankles. This is truly one of the best pair of fitness shoes I have ever owned. Rykas are designed to specifically fit a woman's foot so they are narrower in the ankle area and wider in the toe box. This makes for a perfect fit! Usually when I wear a new pair of tennis shoes for the first week or two, my feet hurt around the ball of the foot. These shoes did not hurt my feet at all. I have been comfortably wearing them for almost a year now. I have worn these shoes for the following activities: a jazz dance class I take once a week, zumba, spinning, running on the treadmill (11 miles a week), using the elliptical, step aerobics, kick boxing, body pump & doing various exercise DVD's at home. The only reason I am actually replacing them is because I have worn the tread down even though the outside still looks new since I do not wear these outside. I ordered my regular shoe size and it fit perfectly. A previous reviewer mentioned that these shoes are very light. I agree. These shoes do not feel like blocks on my feet. I wear arch supports in all of my fitness shoes, but I would consider these shoes to be supportive considering that I have worn them to exhaustion. When I first got them, I didn't really care for the style. I thought the silver trim looked a bit cheap. I almost picked a different pair because of this. Once I wore them, they was no turning back. They are neutral enough to match all of my fitness clothes. I would highly recommend these shoes to anybody who is as much of a fitness freak as I am. Rykas will be the only fitness shoes I put on my feet now.

    Have worn Rykas for years until they discontinued my shoe. Took awhile, but I found the Core Strength Trainer. I love it. Should have heeded the previous reviewers as they were right. You have to order a half size larger and then it is perfect. Hope they keep these around for a long time. And Zappos is one great company to do business with.

    I was looking for a shoe I could comfortably wear at the gym, and I found one in this Ryka. I ordered the shoe in my usual size, and it's a perfect fit. I'm not thrilled with the way they look, but these light shoes breathe and remain comfortable throughout my workout; they do fit the bill.

    I love, love these work-out shoes! They are light and are constructed so that they breathe and my feet never feel hot. Besides their construction and comfort, they are really cute. I have had many compliments on them! Actually, they are the best looking work-out shoes I’ve ever had. For me, they run true to size.

    This is a very stylish shoe. It has a very comfortable heel; it’s snug, which is comfortable on my foot. The toe box is wider than in other shoes, and the shoe does run a good half size small. It provides good lateral support. I use the shoe for core training classes and walking. I recommend it. (I also appreciate the free upgraded expedited shipping from Zappos!)

    I’ve been wearing Rykas for several years and have been pleased with their comfort. Once again I’m very happy with my new Rykas - very comfortable and the color is nice, not so bright white. I always buy a half size larger than I usually wear.
