These socks are so comfortable. I love them for training. The big one fits great. I wear women's size 8/9. I also got them in small for my daughter, she has a 13 year old toddler.
Pros
These socks are a bit pricey for only 5 pairs but they fit my daughter well and she says they feel great.
Cons
Low-cut socks may not provide enough protection and warmth in the colder months.
