Hollow Socks

Bev is an illustrated composite of what Hollow Boot Sock customers tell us.

For feet that are always cold

Her husband calls her feet “the icebergs.”

Bev tried two pairs of wool socks every winter for twenty years. One pair of alpaca put her back out on the pond with her grandkids.

01 · Every winter in Duluth

Biscuit wants his walk at 6. Her toes quit by the mailbox.

The 6 a.m. walk.

Biscuit is fourteen and still wants every lap. Bev makes it to the mailbox before her toes give up.

Two pairs of socks.

Warmer for about ten minutes. Then the boots won’t zip, and her feet feel squeezed and colder than before.

Wool itches.

Then it gets damp. Then it gets cold. Every winter, the same three steps.

02 · Last Christmas

She watched the skating from the car.

Three grandkids on the pond behind her daughter’s house. Everyone out on the ice. Bev in the passenger seat with the heater on, waving through a fogged-up window.

Not because she didn’t want to be out there. Because she knew how her feet would feel twenty minutes in.

More socks was never the answer. A better sock was.

03 · Then her daughter filled her stocking

Alpaca is hollow inside. It holds the warmth and lets the damp out.

  1. 1

    Warm without bulk

    Each alpaca fiber has an air channel down the middle. One pair does what two pairs of wool tried to.

  2. 2

    Stays dry, so it stays warm

    It wicks moisture instead of holding it. Damp socks are what turn cold feet into frozen feet.

  3. 3

    No itch

    Alpaca has no lanolin and a smoother fiber than sheep’s wool. Soft against bare skin.

04 · Why two pairs backfires

Squeezed feet get colder, not warmer.

Pile on socks and your boots get tight. Tight boots press on your feet, and the air that should be keeping you warm gets squashed out. Add a little sweat from the walk and the wool holds it right against your skin.

The Boot Sock is 70% alpaca with full cushion. One pair, boots zip, room to wiggle your toes.

05 · Mornings now

One pair. Boots zip. Toes warm past the mailbox.

06 · This Christmas

This year she’s out on the pond with them.

Snow coming down, the youngest holding her mitten, the other two showing off their spins. Bev at the edge of the ice for the whole afternoon, not the car.

Her husband says he misses the icebergs. He doesn’t.

07 · The stocking stuffer she’ll actually wear

Keep two. Stuff two stockings.

  • For your mom, your sister, the friend who wears a blanket to book club. Anyone whose feet are cold from November to April.
  • Crew height works with winter boots, house shoes and bed. Over-the-calf for tall boots.
  • Gives like a real gift. Not novelty socks. The pair she reaches for every morning.

P.S.Bev’s husband stole a pair the first week. She bought the six-pack so she’d stop finding them on his side of the bed.
