Running Shoe Size Guide

Use toe room, width, socks, activity, and return terms to choose a better running shoe fit.

Measure both feet

Foot size and shape can change over time, and one foot may be larger. Measure later in the day when feet may be slightly expanded, then use the brand's current chart as a starting point.

Check space and hold

The toes need room to move without the foot sliding forward. The heel should feel secure without painful pressure. Width, upper volume, lacing, and sock thickness all affect the result.

Test carefully

Try shoes on a clean indoor surface if returns allow. Walk, jog lightly, and check for rubbing or pressure. Do not rely only on your size in another brand or model.

Buying checklist

  • Measure both feet.
  • Wear your usual running socks.
  • Check toe room, width, and heel hold.
  • Confirm the seller's return conditions.

Frequently asked questions

Should running shoes be a half size larger?

Sometimes, but not always. Foot shape, brand, model, and activity matter more than a universal rule.

How much toe room is needed?

Enough for the toes to move without hitting the front during running. Fit guidance from the specific brand is the safest reference.

Can walking shoes be used for running?

Some models may work for limited use, but running shoes are designed around different movement and impact needs. Choose for your actual activity.
