How to Choose Your Injinji Sock Size
Our sizing guide is based on your shoe size. For example, if you wear a men's size 11, we recommend choosing size 11–13, which corresponds to size L in our unisex size guide.
The Ultra Run Crew toe socks are designed to support long-distance running and high-performance use, offering both comfort and efficiency. They feature Terry Cushioning in the toe and underfoot areas, effectively absorbing impact and reducing fatigue during strenuous road or trail runs.
The construction reduces friction between the toes, minimizing the risk of blisters, while allowing the toes to splay and move naturally for improved balance and movement. The mesh upper fabric enhances breathability, ensuring comfort even during prolonged use.
The socks come in a crew height with a ribbed knit cuff that provides a snug fit and helps prevent dust or debris from entering during runs.
