Double Layer Seamless Toe
Wrightsock's Double Layer styles offer a seamless toe like most performance socks do these days; however, as you can see on the below images, Wrightsock's seamless toe looks a bit different. This is due to the required attachments that connect the inner and outer layers together for our Double Layer system.
Even though it looks a bit odd, our seamless toe acts and feels the same on your foot as any other seamless toe design.

As a decades long Thorlo fan, I was forced to make a reluctant change, as my newer Thorlo socks have not held up like the originals. I was relieved to discover these socks and feel confident I have found a replacement brand for my Thorlo socks.
In these socks, my feet feel good and comfortable and I can already tell they have cut down on the friction of my feet moving around in my shoes. The only issue is they can feel very hot which is something I did not experience with the Thorlo socks.
Years ago when I could run I always wore Wright Running Extra. They protected my feet from blistering and gave me the padding I needed.
These are the only socks I wear now. I don’t get any foot pain or blisters after hours of hiking.
Arrived late so I couldn’t take it on my trip
Soft, strong, best cushion for your soies. No chafing due to double layer so prevents callus formation. No other sock as good…
