I've been wearing the Kayano since the 14 came out. When I heard they were releasing the 21, I had to get them! While I was not impressed with the Kayano 20 (a bit too snug for my foot), the 21 is great! The fit is a lot better, and works with my custom orthodics. I normally wear a size 8 in running shoes, and for me, these seem to fit true to size. They are great for short and long runs; I don't feel fatigue in my feet and knees. Although they are a bit pricy, they are totally worth it! I just bought the Kayano 21 Lite Show, too!!
Was this a gift?:
Bottom Line Yes, I would recommend this to a friend
