Frequently Asked Questions
Can I wear a wrist brace while typing or working?
Yes — many wrist braces are designed for daytime use during work. Softer compression supports allow typing while providing light support. Rigid splints may restrict typing and are better suited for high-load activities or night use.
How do I clean a wrist brace?
Most fabric wrist braces can be hand-washed in cold water with mild soap and air dried. Remove any removable splints before washing. Check the specific care label — some rigid braces can only be wiped clean, not submerged.
Does Medibrace offer free shipping in Canada?
Yes. All orders ship free across Canada with tracked courier delivery in 1–2 business days.
What is Medibrace's return policy?
We offer 30-day hassle-free returns. If your brace doesn't fit or meet your expectations, return it for a full refund. Free return shipping is included.
Are Medibrace products covered by insurance in Canada?
Many extended health benefit plans cover orthopedic braces. Check with your insurer and ask your physician or physiotherapist for a prescription or letter of medical necessity to support your claim.
