Men's Slipper Socks: How to Get the Fit Right

It usually starts with borrowing. A pair left by the sofa, a cold kitchen floor, and a quiet decision that nobody needs to know about. Then the cuff won't reach, the heel sits halfway along your foot, and it's clear you need your own.

If you're shopping for men's slipper socks, fit is the whole game. This guide covers how to choose a size, what to look for underneath, how warm is warm enough, and how to keep a pair soft once it's yours.

Start with your shoe size

Slipper socks are sized like footwear, because that's what they are. The Foozie comes in three sizes, and if you wear a US men's 10 or bigger, the one you want is Large.

  • Kids/Small: US men's 3–6, UK 2–5, EU 35–38, foot length 22.8–24.8 cm
  • Medium: US men's 6–10, UK 5–9, EU 38–42, foot length 24.8–27.3 cm
  • Large: US men's 10–14, UK 9–13, EU 42–46, foot length 27.3–29.8 cm

Between sizes? Go up one. A US men's 10 sits right where Medium ends and Large begins, and Large is the one that will feel right on a cold morning.

Not sure? Measure it

Stand on a sheet of paper with your heel against a wall, mark the tip of your longest toe, and measure from the wall to the mark in cm. Anything up to 29.8 cm is covered by the Large.

Longer than that? Large is our biggest size, so it's still the one to try. And if they don't fit, our 30-day guarantee has you covered.

Don't forget the calf

Foot length isn't the only measurement that matters on a tall slipper sock. The cuff and the calf set the real limit, so if your calves are on the wider side, go up a size there too.

That height is the point, though. The Foozie has a tall sock design for complete foot and ankle warmth, which takes care of the cold gap between the bottom of your jeans and the floor.

What customers with big feet tell us

One of them put it better than we could: "Finally, a warm slipper for these size 12 feet of mine. Love they go up the leg without being tight!"

Another summed up a pair on bigger feet like this: "…a very comfortable product for my size 13 wide feet."

And pink, it turns out, is for everyone: "Wasn’t sure about the pink for men but im rocking them!"

Grips: the part underneath that matters

Hard floors, a quick walk to the kettle, the dash to answer the door before the dog does. That's where grips earn their place. Every Foozie has non-slip silicone grips on the sole, and you'll feel the grip, not the grips.

They're thick, cozy slipper socks for home: not designed to go inside shoes. Think of them as the thing you change into when the work boots come off.

How warm is warm enough?

Warm enough that you forget about your feet altogether. Rated 4.5 TOG, The Foozie is 10x warmer than cotton socks.

TOG is a warmth rating, and ours was measured properly: 4.5 TOG, lab-tested on the finished slipper sock (ISO 11092). Or in our customers' words: "Like an electric blanket for your feet." In plain terms: warm as toast, even on tiles.

Which Foozie should you get?

The Foozie™ is the classic: an ultra-thick plush outer lining and premium sherpa on the inside. Black, Dark Gray and Blue are easy places to start if you like your slipper socks low-key.

The Foozie™ Move is the #1 travel slipper sock. It's slimmer, with a durable diamond cable knit design and cozy sherpa fleece on the inside, which suits long flights and weekends away.

Want a print? The Foozie™ Christmas turns up for the festive season, and The Foozie™ Yum brings snack characters to the sofa.

Buying for him?

Check the size printed inside his everyday shoes, then match it to the chart above. If you're torn between two, go up.

For a teenage son, check again anyway, because his feet may have grown since you last looked. One parent's review sums up how that can go: "Present for my son at Christmas. Took off the others I’d bought and said to me ‘feel how furry these bad boys are’! Praise indeed from a teen 🤣"

And for a partner, the best outcome sounds like this: "You'd think I'd given him the winning lottery ticket! He couldn't wait to wear them."

Keeping them soft

Machine wash cold on a gentle cycle, with similar colors. Air dry.

Use a mild detergent; don't tumble dry, iron or dry clean. They dry slowly because they're so thick, so give them time.
