Have to agree with Joe,...best to find an shoe that fits your foot. I have always struggled with this,..and although I've been wearing Sidi for the past10 yr.,..I've experimented with others,..but Sidi seems to be the best fit for me. Currently an old carbon ergo. Also,..my stoker/wife wears Sidi,..although she wears the mtn version. I use Speedplay on all bikes,..so I only have one pair of shoes,..and she uses spd,..with only one pair of shoes.
