OS1st Performance Foot Sleeve (Pair) – FS6
$49.95
The FS6® Performance Foot Sleeve is incredibly effective at relieving the pain of Plantar Fasciitis, chronic arch and heel pain, and swelling in the foot.
Compression Zone Technology® knit into this amazing foot sleeve provides medical grade orthopedic support to the foot structure and the Achilles tendon. Graduated compression improves circulation and reduces swelling, all in an ultra-comfortable moisture-wicking foot sleeve that can be worn under socks and inside shoes.
The OS1st FS6® can be used for resting therapy or overnight and gives morning pain relief from the first day. Worn as a pair, during your run or sport, FS6® functions as a strengthening support and Plantar Fasciitis preventative.
NOTE : This product comes with (2) compression foot sleeves per package
