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®’s patented Compression Zone Technology uses top-of-the-line knitting machines to precisely create four distinct zones of compression for OS1st® AC4® Active Comfort Socks, 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
