Kayano 23 are TOO SHORT LENGTH and TOO TIGHT INSTEP. Hubby's older Kayano 22's are super comfy and fit like a glove, but this 23 has a more pointy toe and the instep is really tight even on his narrow foot. Sad, because this green color is super fresh & bright and would have looked awesome once he switched out the black shoelaces with neon yellow or orange ones to make shoes really pop!
