Compression Zone Technology®,CZT®
Compression Zone Technology or "C-zone technology" is a patented, evolutionary approach to performance sleeves and socks uses top-of-the-line, precision knitting machines to seamlessly transition levels of compression from moderate to firm within a sleeve or sock to target specific conditions.
OS1st® FS4™ Plantar Fasciitis Socks are made using top-tier precision knitting machines that accurately divide the socks into multiple compression zones.
They provide varying levels of compression and stability to different parts of the foot and joints, helping to relieve discomfort caused by overuse in daily life.
OS1st®’s patented Compression Zone Technology uses top-of-the-line knitting machines to precisely create four distinct zones of compression, delivering targeted support to the feet and joints.
With graduated compression and enhanced joint stability, it effectively relieves discomfort caused by daily activities.
Textile engineering – We patented our technology after extensive research and medical testing on the affects of our targeted compression on Plantar Fasciitis and grew from there.
Advanced equipment – Our products require precision knitting machines which happen to be the most technologically advanced machines in the world
Hydro-transfer system – We select the best Micro-Fiber yarns with moisture-management built-in so there's no chance for sweat to stay trapped in your compression product
Lycra® Energize fiber - Our compression feels like a custom fit because we've woven in specialized fibers to keep it close-fitting and flexible
No bulk – The use of premium materials, targeted zones of compression and top-of-the-line machinery results in sleek, thin products that are still durable yet soft
