I love my Sidi's Genius 4. Both my husband and I have them and they are great. You won't find them cheep but they are worth the buck. They have a great buckle system which you can losen or tighten on the fly. You can find some genius 3 on sale some places they are last year's or even 2001 but they haven't changed much and it will save you $120 if you can find them.
