PERFECT GRIP PremSox are made with revolutionary non-slip chevron technology pads inside and out, which ensure that you are secure in your footwear and your foot doesn't slide. The pads are made with technology that grips as you start to perspire, meaning our socks work better as they acclimatize to your feet. SPEED & AGILITY PremSox allow you to generate greater speed and agility, while making you feel more secure in your footwear, and feel safer that the grip you get from our socks won't let you down at that vital moment.
