This is my first pair of Serrano's by
Asics. I own several pairs of the Ultimate 81's and a pair of Mexico 66's by
Asics, and the Serrano is my favorite of all
Asics' low profile
shoes. The Serrano has a cushy
sole, super light weight, and flexibility unmatched. Another thing I love about the Serrano is that it's the one shoe style by
Asics that doesn't make my feet feel too hot. The mesh on the sides and top is breathable and airy. All I hope for are more colors. Please don't discontinue this
Asics model! I love the yellow/black and the charcoal gray. Looking into buying black/white/yellow also.
