Very happy with my purchase of the Wolvhammer. I ride throughout the snows of upstate NY (US) winters, where temps will often drop to 0 degrees F. My prior winter boots didn't hold the warmth, especially at the toes, so I would have to supplement with a heated insert. These boots are both warm and waterproof. Ordered a 1/2 size up from my normal foot size to accommodate a thicker sock and fit is excellent.
When first looking at boots I was not sold on the clipless option, but these boots have changed my mind.
Overall the fit is as advertised. No need to size up for larger warmer socks, it's already included.
Boots have been warn at 0 deg F and warmer and each time my feet were almost too warm.
The BOA system is quite nice, foot is easy to get in and out of the boots. I wish there were 2 BOAs though like it's warmer brother. The clamping system seems to be quite hard to get snug at the toe section of the boots.
Mud/water resistant up to the little notch in the boot to cuff. At that point the tongue of the boot separates. (just above the second eye in the picture).
I live in the Midwest, we get snow and lots and lots of cold. I have always had issues keeping my hands and feet warm. I've solved the hand issue last year but my feet still continued to be cold. I purchased these boots after getting a recommendation from a guy I met in northern MN at a mountain bike race. I purchased a size larger given I'd be wearing a liner and wool sock.
I've ridding with these boots 250+ miles so far this winter, from temp in the single digits to the mid 20's. My feet have never been cold in these boots - they are remarkable. I have Crank Brothers egg beaters, the boots work great with them (with the required shim).
100% endorsing these boots!
