Got the purple "Wildflower" ones from Whiskey militia for I think $9 +shipping.
Foot size 7.5, I got the XS/S size and they fit GREAT!! No slipping in my boots, stays put on my calf, and they dont go all the way up to my knee where they could potentially scrunch and bunch and cut off circulation (which is a huge problem with buying small men's riding socks... dont do that)so they stop a few inches shy of my knee and I like it that way.
The coolest part of them is the way the knit is on the top of the ankle, its like, an accordian or something. hard for me to explain but it assists in that non-bunching/scrunching quality that is very important for female riders. If you click on the purple one, you can see the detail better, it's like a thinner knit in certain parts so when you bend, it fits together perfectly.
5 of 5 stars.
