Invisible Socks ($13) Despite staying out of sight, the socks protect your feet and shoes, soaking up sweat and preventing your feet from rubbing. The socks have small dimples to prevent them from slipping inside your shoes. Made of 74% Pima cotton, 23% nylon, and 3% elastane. Made in Italy.
Final Thought: The socks was really good quality, but they did slip off on the sides and bunch up on the back of the heel after some time.
