As I’ve discussed in my hiking sock gear advice page and my Blister Prevention Tips page, one of the best way to prevent blisters when hiking is to wear liner socks underneath a bulkier hiking sock.
When I first saw the Injinji toe sock liners at the store, I was skeptical. I wondered how my toes would like having their own individual spot, and whether it would even fit since humans all have such differently shaped toes. I was convinced by the salesman to give them a try, and I haven’t looked back. Now I wear them on almost every hiking trip.
They are constructed so that each toe “sock” is seamless, so there isn’t a chance for rubbing. Therefore, no blisters! Plus, since they are constructed of a mix of polyester and nylon, they stretched to fit my toes perfectly, and of course are highly “wicking” so my feet stay dry in my boots.
The drawback? They’re always sold out! All of my hiking friends are wearing them now, and the word is getting out that these funny looking liner socks are preventing a lot of blisters and unhappy feet on the trail 
REI is not carrying the liner socks anymore, but they are available online at SummitHut. Even though it says “Men’s Liner sock”, they are unisex. A small fits women’s shoe sizes 6-8.5.
If they weren’t so pricey I’d own several pairs (I only have 2 pairs now).
And if you just can’t imagine yourself wearing toe socks no matter how much I swear by them, my next favorite pair of liner socks are the SmartWool liners.
Those are my toe sock liners!
Did they get rid of the white ones? I can’t seem to find them!
They now come in gray and black. The white ones tended to get a bit dirty looking, but the gray ones are great. I love my new gray pair!
