Good to know
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.
