Once Haflete is attached to your legs, you will be forced to maintain position on the front of your feet without the heels touching the ground. Most of your body weight will shift to the front of the feet, immediately activating tension to the two primary calf muscles (Gastrocnemius and Soleus) the entire time you are performing your drills. 

You will be conditioning and strengthening the calf muscles while using Haflete, as well as improving the elastic recoil of the Achilles tendon before your training session. The gastrocnemius and the soleus muscle merge above the heel and attach to the Achilles tendon. You will develop fast twitch muscle fibers in the calf muscles to feel more explosive during your training sessions when you perform drills using Haflete. Fast twitch muscle fibers produce fast and strong muscle contractions to support short bursts of energy involved in movements like jumping or sprinting.

The gastrocnemius and the soleus muscle are powerful plantar flexors (foot pointing downwards) of the ankle. The two muscles help generate positive ankle power when running, jumping, and changing direction. The resistance cables connection from the Haflete footwear and Haflete knee brace allows you to perform stretching exercises to target the tibialis anterior. The tibialis anterior is the main dorsiflexor of the ankle (pointing the foot upwards). Dorsiflexion produces stability and strength in the ankles while helping to reduce ground contact time per stride.
