By guiding the heel bone towards the talus, it creates a better joint surface, aims for a straight line from the heel to the ankle, forms the arch of the foot, and improves performance during exercise. It also stabilizes the foot, improving posture and reducing pain in the knees and hips. I was interested and purchased it, but I've only worn it a few times for a short period. *Name is written on it. - Product Name: Magic Jumper Pro - Support Type: Foot Supporter - Color: Black - How to Wear: Easy to wear - Features: Posture stabilization support Thank you for viewing.
