Injinji
Injinji socks can be useful in preventing certain types of blisters. The unique feature of Injinji socks is they have a separate compartment for each toes, and are sometimes called "toe socks." This feature can help reduce blisters between the toes, but ironically the extra thickness of material between each toe can actually increase pressure on the toes and makes things worse. Therefore it's important to use the thinnest of the Injinji socks, the Injinji liner sock. Other than the individual toe compartments, the Injinji is a regular single-layer synthetic sock, so it won't help with blisters in other areas. The key is to combine the sin Injinji liner sock with another thin sock so that you have two layers of material, which helps prevent blisters in other areas. I've found that the ultimate protection comes from combining the Injinji liner with a Wrightsock is double layer sock, giving three layers to reduce friction. The Wrightsock Coolmesh socks are remarkably thin, or you can use the slightly thicker Wrightsock Silver Elite. I use both the Coolmesh and of the Silver Elite, which allows me to tweak the fit of any particular shoe slightly, another critical aspect of Blister Prevention.
