When winter kicks it up a notch, Merrell Isotherm Zip waterproof winter boots kick in. Whether you work or play outside in winter, your comfort absolutely depends on your ability to stay warm and dry, starting with your feet. Isotherm 8s have you covered, with a completely waterproof shell, generous Primaloft® insulation, and a heat-reflecting insole. And they go farther, with comfort features like a compression-molded EVA footframe, air cushion in the heel, and a bellows tongue to keep debris out of the boot. For snowshoers, Merrell has added a snowshoe-strap ridge for extra stability. And for the style conscious and lacing-challenged, Merrell offers the front zip, which gives the boots a sleek profile and makes them even easier to get on and off.

  • Full-grain leather and pig suede upper
  • Front zip entry
  • TPU waterproof shell locks moisture out of the shoe, but remains breathable
  • Generous Primaloft® insulation (400g) for lightweight warmth
  • Fleece lining
  • Lining is treated with Aegis® antimicrobial solution to prevent odors

  • ActiveHeat® insole uses silver reflective film between insulating polyester

"It may come in wider sizes as offered by Merrell, however we only carry regular widths. "

"I clicked on your sizes chart but what came up were sizes that relate to clothes. How do I relate these clothes' sizes with shoe sizes? I wear shoes in the 8 - 8.5 UK size range with a foot that measures 27 cm in length. How do I use your chart to find out what sizes of shoes I should order?"

"These boots do run true to size. If you plan on wearing them with thicker winter socks or if you are between sizes then we would recommend sizing up!"

Average Customer Rating: 5/5 (4 customer reviews)
Comfortable and easy to slip on   Rated: 5/5

The zippered boots are very comfortable and easy to slip on and off. No more soggy shoe strings... Non laced shoes are a new favorite of mine.

Warm and comfortable but they break down quick   Rated: 3/5

This is a great boot, it is very comfortable, warm and water proof. I bought a pair last year and I worked in them all winter. They were more comfortable than my work shoes, so I wore them all summer but they broke down in fall. The left shoe separated from the sole and now leaks! I am so sad, I want to buy a new pair but maybe I'll try the shiver boot.

Typical Merrell - Great Quality   Rated: 5/5

Been buying Merrell for 20 years and every one has been a good-to-great shoe. This is a great shoe new, ask me again in 2 years to see how it holds up.

Excellent boot    Rated: 5/5

Really comfortable boot. Very happy with the purchase.
