Why Weightlifting shoes?
Weightlifters have realised that a shoe with a raised heel to allow the "flat footed" tilting of the shin was required for more balanced, consistent and heavier lifts. The raised heel facilitates the "flat footed" bending of the ankle joint and at the same time a fuller extension of the muscles of the leg, hips, pelvis and lower back for better technique. The weightlifter moves his feet apart and fully bends the knees, hips, and ankles to squat down to "receive" the bar at the chest for the clean or overhead for the snatch. Effective technique requires the forefoot to be flat on the floor in "deep split" and "deep squat" styles. The weightlifter can lose balance very easily if his/her heels rise from the floor in the deep squat position. A shoe with a raised heel allows the weightlifter to squat down with a vertical trunk, full extension at the knees and shins tilted forward.
Please note: you should not attempt to lift heavy weights without the right equipment and expert supervision.
