My son is 12. Will Jumpsoles or Proprioceptors stunt kids growth?
Definitely not. Jumpsoles and Proprioceptors are designed to build muscles safely through natural standing, walking, & jumping on their own body weight. Danger of stunted growth occurs when kids try to lift unnaturally heavy weights which their bones cannot support before their growth plates have closed. As long as he stays clear of trying to lift heavy extra weights, your son will grow to his genetic height.
