Kitletics Review · 8.4 Good
Injinji Run Midweight is a running sock. Toe-sock design that separates digits to reduce between-toe friction on long runs. I'd shortlist it for separates toes to limit hot spots. The trade-off is adaptation period for first-time toe-sock users — Feetures Elite Light Cushion is the cleaner compare when that is most of your week. It fits buyers who actually need a running sock, not a one-product rotation.
