Insoles for wide toe box shoes

The best insole for a wide toe box keeps it wide

Most insoles are cut for a standard last, so in Altra, Topo or Lems they leave the forefoot bare or have to be trimmed down. Blumaka's Wide Toe Box Insole is shaped for a roomy forefoot. Your toes keep their room to spread, the heel stays locked in, and you get real arch support in three heights.

What to look for

What makes an insole right for wide toe box shoes?

  • A forefoot as wide as the shoe. A standard insole leaves gaps at the sides of a wide toe box, and your foot slides into them.
  • A heel that stays narrow and deep. Wide toe box shoes still need the heel held in place. Look for a deep heel cup.
  • Arch support you can choose. Stock insoles in most shoes are a thin, flat layer of foam. Pick a low, medium or high arch to match your foot.
  • Thin enough to keep the fit. A thick insole steals the room you bought the shoe for. Check the stack height before you buy.
  • Foam that holds up. If the insole packs flat after a few hundred miles, you are back where you started.

Will it fit my shoes?

Which shoes is it made for?

Altra, Topo and Lems

This is what it was shaped for. If you run or walk in a wide toe box shoe and want more feel and arch support than the stock insole gives, swap it in without cutting down a standard insole.

A note on drop

The insole is 8 mm at the heel and 4 mm at the forefoot, so it adds about 4 mm of heel-to-toe drop. In a zero drop shoe like Altra, that is worth knowing before you buy.

Vivobarefoot, Xero and other barefoot shoes

If you want a little cushioning in a barefoot shoe, it adds some. Check that your shoe has room for the extra stack first.

Got questions?

Straight answers.

What is the best insole for wide toe box shoes?
One shaped for a wide forefoot, with a deep heel cup, a choice of arch height and foam that holds up. Blumaka's Wide Toe Box Insole is built for that: a wide forefoot for Altra, Topo and Lems, 8 mm at the heel and 4 mm at the forefoot, three arch heights and a 1,000-mile cushioning guarantee.
Will a regular insole work in a wide toe box shoe?
It fits, but it usually leaves gaps at the sides of the forefoot, and your foot can slide into them. A wide forefoot shape fills the shoe the way it was built.
Does it work in Altra shoes?
Yes. It was shaped for Altra, Topo and Lems. Altra shoes are zero drop, and this insole adds about 4 mm of drop (8 mm heel, 4 mm forefoot), so keep that in mind if you want to stay fully zero drop.
Which arch height should I choose?
Pick Low, Medium or High to match your arch. You have 90 days to make sure it is right.
Can I use it in barefoot shoes?
Yes, if you want a little cushioning in a Vivobarefoot, Xero or similar shoe. Make sure the shoe has room for the extra stack.

It is backed by a 1,000-mile cushioning guarantee and outlasts 3-4 pairs of running shoes. See how long Blumaka insoles last and the full data.
