Our take on the Oboz Big Sky II Mid Insulated B-DRY Winter Hiking Boot

The Oboz Big Sky II Mid is a 7-inch insulated winter hiking boot built around a waterproof full-grain leather upper, 200g PrimaLoft Bio synthetic insulation and a Vibram Megagrip Granite Peak outsole. Oboz's O FIT Thermal insole adds an insulated top sheet and a Mylar layer that reflects heat back to the foot, while the ACT Impact PU midsole is tuned for cushioning and rebound on long days. Stretch panels and pull loops ease entry. It suits cold-weather day hikers and snowshoers who want warmth and grip without a full mountaineering boot; against lighter three-season hikers it is warmer and more weatherproof but heavier and less breathable.

About the Oboz Big Sky II Mid Insulated B-DRY Winter Hiking Boot

The Big Sky II Mid is a 7-inch insulated winter hiking boot. It has a waterproof full-grain leather upper and 200g of PrimaLoft Bio insulation. Stretch panels and pull loops make it easy to put on.

The Vibram Megagrip Granite Peak outsole is built to be supportive and protective, and it grips cold, slick terrain. The Granite Peak ACT Impact midsole uses Intelligent PU for lightweight cushioning, durability, support and rebound.

The O FIT Insole Thermal is molded to the shape and construction of each pair. Its insulated top sheet adds warmth, and a Mylar bottom sheet reflects heat back to the foot. The B-DRY waterproof system lets sweat escape while keeping moisture out.

Questions and answers

Is the Big Sky II Mid warm enough for below-freezing hikes?
It carries 200g of PrimaLoft Bio insulation plus an insulated insole with a heat-reflective Mylar layer, which is aimed at cold winter days and packed snow. It is a winter day-hiking boot, not an expedition boot, so pair it with warm socks for deep cold.
How does it differ from the Big Sky Low?
The Mid uses a 7-inch leather upper with 200g of PrimaLoft Bio insulation. The Low version uses 100g, so it is lighter and less warm but gives up ankle coverage.
Is the boot actually waterproof?
Yes. Oboz pairs the full-grain leather upper with its B-DRY waterproof membrane. Keep the leather conditioned and the membrane intact, since scuffs and neglect are what let water in over time.
Will the Vibram Megagrip outsole hold on icy trails?
Megagrip is a sticky rubber compound that grips well on wet rock and packed snow. It is not a substitute for traction devices on hard ice, so carry microspikes for icy sections.
What is the O FIT Thermal insole for?
It is Oboz's shaped footbed with an insulated top sheet and a Mylar bottom sheet that reflects heat back to the foot. It adds warmth underfoot and can be swapped for a custom orthotic if you need one.
Does it fit true to size?
Oboz builds its O FIT insole to the specific last of each model, so the boot is designed around that footbed shape. Try your normal hiking-boot size and account for thicker winter socks.
Where is the Oboz Big Sky II Mid Insulated B-DRY Winter Hiking Boot cheapest?
