The average person takes about 6000 steps each day. For some, those are painful steps felt in the arch and heel area with notable swelling and discomfort. The OmniForce® Plantar Facia Support Sock targets those areas with focused compression (20-30mmHg around the arch & 18-20 mmHg around the ankle). That means you get comfortable support. May be worn all day, under or over socks.
