Sizing

Get the fit
right

Go by your boot size. If you're between sizes, size up — a sock that's too tight loses grip and comfort before it loses anything else.

Mid-calf · $49.95
Long

Sits above the boot. Pick this if you wear lace-up work boots or gumboots, or you want the extra coverage.

Ankle · $39.95
Short

Sits at the ankle. Pick this for slip-ons, warmer sites, or wearing them around the house.

Not sure?

Between two sizes?

Go up. Never squeeze into the smaller one.

Wide feet or orthotics?

Go up. They should feel snug, not tight — the grip does the holding, not the compression.

Still stuck?

Message us with your boot size and we'll tell you straight.

Wrong size?

Send them back. Unworn, 30 days, we'll swap them. No receipt gymnastics.
