well tbh. haven´t worn mine in winter yet, but shouldn´t be so bad...and the feel?! feels like every other "normal" sole imo.
nothing special and you don´t really notice that there´s a different profile as on a normal gum sole...
but if you´re looking for some "good" soles for winter, then i´d suggest a vibram 100 sole.
vibram 100 vs. vibram 430
