Injury is often not too far away in sports involving high impact forces. Activities such as running can subject the body to a large amount of force, especially in those landing heel first. This is where the Mueller Pro heel cups are able to help out. The innovative waffle design absorbs the high impact upon heel strike, reducing the amount of ground force acting on the body. The benefits of this are two fold; firstly this can greatly minimise the risk of sustaining injuries of the lower limbs such as; achilles tendonitis, plantar fasciitis, flat feet, heel pain and bursitis. Secondly, performance can be improved by increasing forward energy return on impact. The Mueller heel cups are available in two different sizes; regular and large, based on the individuals body weight. Regular = under 175lbs/80kgs Large = over 175lbs/80kgs
