Is the Kamik Trek Ice good for icy sidewalks?

Yes. The deep-lug TREADLITE outsole uses Kamik's GRIP ICE compound, which is made for slippery surfaces. It grips packed snow and ice better than a standard winter boot sole.

Are these boots truly waterproof?

Kamik rates the upper waterproof, so snow, slush and shallow puddles stay out. Water can still enter over the top of the high shaft in deep drifts.

HEAT-MX thermal insulation is designed for winter cold and suits most wearers down to freezing and below. They can feel too warm indoors or in mild weather.

Do they fit true to size?

They generally run true to size, but the high-cut lace-up design fits snugly. Try them with the socks you plan to wear and size up if you want extra room.

Yes for winter trails and snowshoeing on moderate terrain. They are not rigid enough for steep technical mountaineering.

What is the difference from a regular winter boot?

The Trek Ice adds a hiking-style lugged sole, ankle support and reinforced toe and heel zones. That makes it more stable on uneven ground than a casual snow boot.
