Size 10 US, 43 1/3 Euro but seems about 1 size smaller.
I‘ve used them 4 times so they have less than 30 miles on them but I needed a size larger.
Double wall insulating construction
Fiber glass, phylon, polyurethane and nylon upper
Padded collar with pull-on loop
Vibram® rubber outsole
Compatiable with strap on crampons or hybrids as they do have a welt at the heel
