Description

Do you have pain in your knees and joints? Do you want to protect your knees during your sporting or professional activities?

Discover this revolutionary pair of knee pads:

  • It provides extra support to relieve one of the most fragile parts of the body: the knees.
  • Find the lightness in your step while hiking, jogging, or while working.


ADVANTAGES AND BENEFITS

Innovative technology: The knee pads are inspired by military technology that allows soldiers to carry heavy loads for long periods of time while unloading the joints.

Relieves pain: The knee pads feature a triple-spring protective sleeve that makes you feel light and gives you maximum support during weight-bearing. This helps relieve pain caused by arthritis, osteoarthritis, tendonitis, meniscus tears, prevention of overextension, etc.

Robust and durable: it can lighten your weight by about 40 kg! It allows you to easily lift each knee while you are active.

Knee protection and reinforcement: the knee pads are equipped with lateral stabilizers and silicone pads to ensure ideal knee support. With these knee pads, the risk of knee injuries is reduced.

  • Helps improve patellar tracking
  • Supports the knee joint during flexion
  • Provides support during standing
  • Helps reduce stress on ligaments
  • Open knee allows air to circulate for comfort
  • Reduces the risk of a knee injury.
  • Ligament Support Knee Braces for Sports and Osteoarthritis

Comfort: The knee pads are lined on the inside with non-slip and breathable fabric. This provides perfect support for the knees while preventing chafing and odours. The support springs effectively reduce pressure on the thighs and calves.

Suitable for everyone and everything: The knee pads are suitable for top athletes as well as for older people or workers who are used to lifting heavy objects. Whether at the gym, jogging, hiking, or on a construction site, knee pads are the ideal ally for relieving and protecting your knees.

Easy to use: put the knee pads on, adjust them with the Velcro fasteners and enjoy a previously unattainable feeling of lightness.
