You barely notice they are there but they do one heck of a job when you’re out there for hours and hours on the trails" - Scotty Hawker, 5th 2022 Thailand UTMB 100k, 2nd 2021 CCC , 3rd 2019 UTMB "I am a huge believer in the T8 commandos. I used them for months running 40-50 miles a day on the 2,197 mile Appalachian Trail and they never let me down. Soft, comfortable and easy to clean they helped me stay happy and healthy for the journey" - Michael Wardian, multiple time US National 50K champion And check out this review from Middle of the Pack Runner: Sizing: Please note we use Asian sizing, which can be up to half a size smaller than western sizing.
