More important than any other factor - even weight - is fit. Ive found that Merrell's tend to fit my feet perfectly. They also come in a plethora of variants for each shoe series. Example, the Reactor series has models that are low top, mid top, mesh uppers, gore-tex, sandals, whatever... even mocs and slides.
So.. summer or winter, I wear Merrells with Smartwool.
If Merrells fit your feet, youll probably find one that fits your needs (including ankle support).
