I bought a pair at Fleet Feet and absolutely loved them based on comfort. I have sciatic nerve damage and the added comfort helped relieve a bit of the nerve pain in my right foot. I ordered 10 more pair in nearly every color. The picture of 8 of them shows the sizes variations between colors. All of these are size Large. The yellow is considerably smaller then the rest and the blue was too large. The last picture shows identical product where the bottom sock is new, and the top sock is after 2 washes. Significant peeling after only 2 washes. Hopefully they hold up and the $140 I just spent wasn’t a waste.
