How Many Ways Will You Benefit?

”I’ve never gotten a stretch like this. The stretch is so much better and deeper than anything else I’ve used. Great design and amazing quality”

The Anatomy Of CastleFlexx®

Why CastleFlexx® Is Different

Patented

Hammock Stretch For Plantar Fasciitis

CastleFlexx® is the only device with a unique patented "foot hammock" that is completely velcro free. Our foot hammock gives you the ability to fully flex the toes back, resulting in a stretched plantar fascia.

“As a 59 year old plumber with flat feet, I’ve had a lifetime of sore feet and chronically tight calves and hamstrings. Castleflexx has been a blessing and godsend for me!”

Jeffrey

Compact

Rolls Up For Easy Access

No need to store awkward bands or devices that take up space and end up getting tangled. CastleFlexx® rolls up neatly for storage, and can be ready tor use in seconds.

“Super happy with my CastleFlexx - it’s so convenient! I love to take it on hikes and it allows me to walk father and hike multiple days in a row.”

Jess

Comfortable

Ergonomic Design, Soft Handles & Fabric

CastleFlexx® is velcro-free and does not require any strapping in or out. CastleFlexx® has a patented handlebar with optional magnetic weights that provides a controlled comfortable stretch and it wont slip out of your hands like rope straps can.

“The build quality of this is amazing. The bar is heavy, smooth, and looks like a piece of Apple kit. The fabric is soft and dense, and the foot pocket is so comfortable.”

Jesse

“Worth its weight in gold. I use mine everyday, twice a day and I feel more relaxed, looser and ready to tackle what’s ahead. It’s simple, but it works!”
