My bad review for Toasty Feet insoles
I know I'm gonna get flamed because they have a lot of happy customers out there.
I'm a mild pronator. Their standard version is plenty warm but has no arch support. Their arch support version is a joke. After a couple of days straight without a good arch support the ligaments in my feet begin to ache.
Also, the fabric laminated to the top causes my socks to bunch up beneath my feet. This is especially true when I'm going out of my way to maximize warmth by leaving my socks bit loose and then not lacing my shoes up as tight as I could.
I'm going back to my Superfeet Wintergreens and Redhots. They're not as warm but they're ubercomfortable IMHO.
