The North Face Shellista V Mid Boot vs Merrell Siren 4 Thermo Mid Zip Waterproof

Both are 200g-insulated waterproof women's winter boots at nearly the same weight, so the choice comes down to fit and terrain. The Shellista V Mid is the taller, more cushioned boot with a full leather-and-suede upper and a high-pile fleece collar, which owners like for deep snow and long walks. The Siren 4 Thermo Mid Zip is lighter-feeling on the foot, has a side zip for quick on and off, and its Vibram Icetrek outsole is the stronger pick on packed ice. Buy the North Face for warmth and coverage; buy the Merrell for icy sidewalks and easy entry.

• Choose the Shellista V Mid if you want a taller, fleece-lined boot for deep snow, cold commutes and all-day walking.
• Choose the Siren 4 Thermo Mid Zip if you deal with packed ice and want a zip boot you can pull on fast.
