Direct answer: OS1st makes bracing socks and compression sleeves that build orthopedic support into wearable layers, including the FS6 plantar fasciitis sock, BR4 bunion sock, and KS7 knee sleeve. Medibrace carries OS1st in Canada as an authorized retailer, with authentic products and sizing guidance.

About OS1st
OS1st takes a different approach to bracing: instead of straps and shells, it knits zoned compression into socks and sleeves, so support disappears into what you already wear. The FS6 targets plantar fasciitis, the BR4 cushions bunions, and the KS7 supports the knee. They suit people who want all-day comfort without a visible brace, and everything we stock is authentic through the authorized channel.

FAQ
Is Medibrace an authorized OS1st retailer in Canada?
Yes. OS1st at Medibrace is authentic and sourced through the authorized Canadian channel.
Do OS1st bracing socks replace a brace?
They provide light, wearable support. For instability or injury recovery, a structured brace gives more control; many people use both for different days.
