An absolutely amazing product, a complete game changer. Such a simple idea - you don't have to stretch your calf first, it hits everything at once. Incredible!

Unlike isolated stretching, Castleflexx stretches the entire posterior chain of the lower limb making it THE functional stretching tool on the market.”

The CastleFlexx is a great tool for hip mobility, hamstring tightness, tendinosis and plantar fasciitis. It's one of the best stretching devices out on the market today! We use it with all of our patients here to help improve their quality and treatment plans.

Are you ready to feel the best you've ever felt? CastleFlexx is a revolutionary product that helps you become more mobile, more flexible and alleviate chronic pain in a way I never thought possible.

It's unreal, I've never felt a stretch like this. I feel loose, I feel like a spring. I can go do anything without any tightness.
