Freerider Elements XVis dry out quicker, and are very grippy on the bike. Off the bike, well that’s another matter….
Teva Links are more weather proof than Impacts, but no where near waterproof or barely resistant. Probably warmer too.
Both have stiffer soles than AM41s, which will also get wet quickly, but will dry out quicker than Impacts. I found AM41s harder to pedal in, but liked the way you can more easily feel your pedal through their sole riding DH.
Should it really be so hard for someone to come up with a descent all weather flat shoe that isnt basically a walking boot? I’ve got a lovely pair of Northwave Celcius in my loft that I no longer use since changing to flats, I’ve thought about finding out if I can get them resoled.
