How to measure your feet

  1. 1

    Place your feet on a piece of paper with your heel against the wall, standing up.

  2. 2

    Place a flat object such as a hardcover book against your toe so it sits at a right angle to the ground, then make a mark on the paper.

  3. 3

    Measure the distance from the wall to the mark on the paper.

  4. 4

    Choose your size in the table below, based on the β€œheel-to-toe” range.

This range already includes the necessary room in the shoe β€” you don't have to add extra buffer to your measurement.

LiDAR

Fastest way to be sure

Scan your foot with the LONO app

Your phone camera or LiDAR reads your exact heel-to-toe length in about 30 seconds, then suggests your LONO size β€” model by model. No paper, no ruler. Free, iPhone only.

Disclaimer: Any sizing recommendation β€” from the app or from our team β€” is based on the measurements provided and general customer feedback. Fit preferences vary and we cannot guarantee a perfect match. Under no circumstances does receiving sizing advice waive our return policy; customers remain responsible for return shipping costs in the case of exchanges or returns.

Size charts & dimensions

Each family fits a little differently. Find yours below β€” and note that the two families give opposite advice when you're between sizes.

FLOW / FLOW S / EZY / VERVE

Between sizes? Size up

All four models fit true to size. FLOW and EZY are designed for more casual use and are slightly more generous in volume; FLOW S and VERVE have a tighter, more secure fit.

WILD / WILD Lite / NOMAD

Between sizes? Size down

WILD and NOMAD fit higher-volume feet despite sharing insole dimensions with FLOW and FLOW S. Because of that extra volume, if you are between sizes we suggest taking the smaller size. We also recommend thicker socks with WILD.
