Great product - La Sportiva Blizzard GTX Running Shoes - Men's

I wear an 11 in normal La Sportiva, and i ordered an 11.5 based on other reviews. The 11.5’s fit fine, but I probably could have gotten away with my usual 11. I wear a normal Smartwool PhD sock with toe and heel padding. These are very warm, nice cushion, and the spikes that are built in do a decent job. If you’re really worries about going down while running, I might consider throwing a few more spikes on (there’s room for that). The laces also are nice and aren’t slippery- they stay put. Haven’t gotten any snow down my ankles yet.
