Ok, the price caught my eye because most places charge close to $20 a pair. I liked that they were plan and tall... I have been practicing hiking in the So Cal area and these past few months have been pretty chilly, I love how they feel on my feet and keep them at a comfortable temp ... my hiking boot is a size larger and my feet feel perfect in them. Bought these for my first 6 day hike in Northern Spain. I just ordered another package. Going to give as Christmas presents this year... I bought an ankle version from a local hiking shop, expensive, they are ok, I just like these more. I fold the tops down above my hiking boot, looks nice too! Also, they do shrink a little in the dryer, but I like them more snug for my size 8 feet. They stretch out a little after wearing all day. Breath well in hot & cold weather, and not going to wear a liner dock. I wear them to bed on cold nights and around the house...  although, I do wish they were made in the USA!
