I have been wearing the gel-kayano shoes the past several years and have always loved them but these were awful! My last pairs were 19 and they were great but the 21 have changed drastically and left my feet in excrutiating pain. I went on two walks with them and could hardly make it home. Another thing I noticed was my feet slipping inside the toe box and rubbing more than normal on the bottom of the shoe. I ordered the same size and width as I always do but these just did not fit right and felt super hard and stiff. Luckily I will be able to return them and am purchasing the gel-nimbus instead from Amazon. This time I went to a store and compared the two and the nimbus had a ton more cushin and felt a lot better at the store so I'm hoping these work out .
