Choose a sock model, then use its size chart. This guide includes 3 Injinji models, with their material, cushion and layer differences kept separate.
A five-toe trail sock with a synthetic blend and a cushioned footbed.

Keep in mind: Separate toe sleeves need to sit fully on each toe. Position them first, then check that the shoe still leaves toe room.
A lightweight five-toe liner with 74% merino wool, intended to wear alone or under an outer sock.

Keep in mind: This is a thin liner for use with an outer sock. Check the complete two-layer fit and choose a standalone sock if you do not want a second layer.
Injinji Men's Liner + Hiker Crew
A synthetic toe liner and a separate wool/acrylic outer form a two-sock system.

Keep in mind: The outer sock contains wool. For a wool-free setup, choose a fully synthetic pair rather than relying on its synthetic liner.
The lookup includes unisex and men’s Hiker and Runner charts. Match the chart to the exact model, then check the heel and toe fit in your footwear.
unisex: Injinji advises sizing up between sizes. Position each toe sleeve before pulling the heel into place. A plus sign is an open-ended range printed by Injinji.
men’s Hiker and Runner: This combined-size chart applies to the men’s Hiker and Runner constructions. Injinji advises sizing up between sizes. The upper ranges carry a printed plus sign.
Open the brand size lookup. See the fit checklist for heel position, toe room and cuff clearance.
Wash on a cold, delicate cycle and line dry. For the removable Liner + Hiker set, wash and dry the two components separately.
A different instruction on the exact sock takes precedence over general brand guidance. Use the care lookup and your own drying estimate in the rotation planner.
The limited warranty lasts one year for direct or authorized-seller purchases and requires dated proof of purchase. Normal wear, improper care and accidental damage are excluded. A replacement does not start another warranty.
Injinji.com accepts returns within 60 days of receipt, in new condition and original packaging. Final-sale items are excluded, so inspect size and toe alignment before wearing outside.
