Improved circulation

Improved circulation

Thanks to their shaped fit design, OS1st® Performance Compression Sleeves promote excellent circulation. An OS1st® compression sleeve is safer to wear than heavier orthopedic supports.  Our compression sleeves never bind at your body’s natural angles.

Proper circulation is important for maintaining and rebuilding muscles. Within your veins there are valves. If the valves become damaged or weak, compression, prevents swelling, giving them a boost and helping them to be more efficient. More blood flow back to the heart can improve your health. It can also speed up the healing and recovery process. A sports foot compression sleeve will support your muscles while they work hard. The high-performance design delivers different zones of compression.
