My son had told me about point6 socks because he and his fiance do a lot of hiking in Montana. As I was planning a trip to go with them out there, I thought I should also be "sporting" a pair of these little socks. But because I have small feet (size 5), I thought maybe I could save a couple $$ by purchasing kids' size socks. Low and behold, they fit PERFECT and kept my feet nice and warm, but not hot. I LOVE them and would recommend them to anyone looking for a nice wool sock to wear while hiking or wearing boots of any kind. I loved them so much I bought another pair! :)Wonderful warm socks!I bought Point6 Kid's Medium Cushion Crew socks, size large. They were thick, plush, well-constructed, good fit at the foot area, but tight at ankle & lower calf. The tightness hurt me and left deep marks on my skin within 10 minutes. Therefore I had to return the socks to amazon. It was a smooth return process: return online, generate and print a free UPS shipping label with bar codes, drop off the sock envelop, get a Visa refund in 3-4 days. I may buy mini crew or no show Point6 Kid's socks to bypass the ankle/calf tightness. Here are my info:Short, petite adult femaleShoe size: 5.5Ankle circumference: 7.25 inchesMidcalf circumference: 11.5 inchesVery happy. My daughter has narrow feet and gets blisters from a lot of her shoes. She wore these with her new hiking boots and didn't have any problems. Said they were comfortable.Nice color, good fit, but a but loose. Which is nice since she can grow into them. She's 2.5 years old, and tall/big for her age.I bought these for my five year old son who is not used to cold, snowy NY winters. They are great. They keep his feet toasty and they are so soft and comfy.My son love them , he wore them during sky trip and it was perfect. We bought 3 pairs. I will buy more when he is biggerSeem to be a good pair of socks! They're comfy on the kid, well made, etc etc
