I was fitted for a custom knee brace by the Icarus team after going through my third ACL and meniscus repair surgery. The brace was delivered quickly after my initial assessment, and I’ve been using it for plenty of activities like hiking, yoga, and surfing. It’s held up extremely well and it’s helped me manage my knee pain! I highly recommend this company.

This brace takes my knee pain down a full step or two (depending on the day) on the pain scale–it lets me go for hikes and long walks and even keep doing aerial arts. It’s the best mobility aid I own, hands down. They even drove two hours to measure, deliver, and fit the brace, and met me in my office.

The staff at Icarus are wonderful, as well…If you experience knee pain or discomfort- I highly recommend getting in touch with Icarus. It will change your life!
