The bestselling PROFORMANCE Meryl Skinlife Socks collection has a brand new addition. These XTRA COOL socks are lighter and more breathable than its predecessor and are therefore your choice of socks in summer conditions. The Meryl Skinlife fabric is known for its antibacterial properties, which keep the socks fresh, time after time. The socks have a soft feel, which provides — along with breathability and stretch — great comfort. The socks manage moisture well and have an open structure, which offers superior ventilation. Last but not least, thanks to the reinforced panels on the heels and the toes, the socks will last a long time.
