In FrostVentureNo hard shape pressing on one spot all day. -
A stiff sole stops your foot bending, so the work travels up into your lower legs.

What to expect
The first two weeks

Wear them round the house. Insole in.
Day 4 to 7
Half a day
Insole in, and add a short walk outside.

Insole out on a milder day.
Day 15 on
All day, every day
Insole in when it is frozen.
Why it works
What FrostVenture actually does for your feet
Warm all the way round, not just underneath
Plush fleece lining, windproof build.
Your toes still splay, even in winter socks
Room for your toes and thick socks.
Sure footing on snow and wet rock
Deep lugs bite into snow, ice and rock.
01 · The sole
Two boots in one pair, and you decide which one you need today
The thermal insole in FrostVenture lifts straight out. Leave it in when the ground is frozen, take it out when you want less between your foot and the ground.
Then leave the thermal layer in and forget it is there
A warm fleece layer underfoot on top of the EVA, so cold never comes up through the sole. This is where the boot spends most of the winter.
Then lift it out and there is less between you and the ground
Two seconds, no tools. You get more room for a thick sock, more ground feel underfoot, and the insole can dry overnight instead of staying damp inside the boot.
Either way your heel and your toes sit at the same height, the way they do when you stand on your own kitchen floor with nothing on.
The weight
You do not wear your boots. You lift them, about 7,000 times a day.
A normal winter boot adds a few ounces. Multiply that by 7,000.
18 oz per shoe
Weight you stop lifting, every day
0 lb
One shoe per step, at 7,000 steps a day.

Questions
FrostVenture questions, answered
How warm are the FrostVenture boots?
Warm and cozy for everyday winter. The plush cotton insulation lining holds heat well, and the mid ankle height keeps warmth in without feeling heavy, so they suit daily cold weather wear.
Are they waterproof or water resistant?
They are water resistant. The elastic fabric, nylon and webbing upper has a water resistant coating that handles light snow and rain. They are not fully waterproof, so we would keep them out of deep slush and standing water.
How do they grip on snow and ice?
The thickened textured anti slip rubber sole grips snow and wet pavement for steady footing. It is dependable on winter walks, though we always advise care on solid ice.
Are these truly barefoot boots?
Yes. FrostVenture is zero drop with a wide toe box and a flexible sole. Your toes can spread and your foot moves naturally, and the elastic locking laces let it flex with you.
What size should I choose for thick socks?
They fit true to size for most people. If you wear thick socks, or you are between sizes or have wider feet, size up a half size for more room. Women and men have their own sizing, switched with the Women and Men buttons at the top of the page.
How do I care for the upper and lining?
Wipe the fabric and nylon upper with a damp cloth and let the boots air dry naturally, which keeps the water resistant coating working. Let the cotton insulation lining air out between wears and keep them away from direct heat.
Can I return them if they do not fit?
Yes. You have a 30 day money back guarantee. Send them back within 30 days for a full refund. We ship to the US and CA.
