We’ve worked tirelessly to develop socks that match the same quality, comfort and attention to detail as our classic Mantra slide style. Our socks offer premium quality, exceptional durability, along with added arch and ankle support, wrapped up with moisture wicking, antimicrobial properties to help stop the stink. To top it all off, our socks are designed, produced and printed in the USA. Small = Men’s Shoe Under 5 Medium = Men's Shoe 5-8 Large = Men's Shoe 9-11 XL = Men's Shoe 12-14 XXL = Men’s Shoe 15
