I recently started jogging and have been struggling with blisters. So frustrating! I first purchased better running shoes and that helped some, but I have not gotten any blisters since purchasing these socks! I am so happy to have found these and will be ordering more soon. I purchased the white, they are soft and are the perfect thickness. My shoe size is a 7, the medium fit perfectly. The socks also seem to be well made. I originally thought the price was a little steep, but I was wrong... These socks are worth every penny!
