Perhaps the type of shoes worn by Olympic weightlifters is their most distinctive piece of equipment. Weightlifting shoes are typically designed with a raised heel of 0.5 to 1.5 and one or two metatarsal straps that tighten across the instep of the shoe. The raised heel helps the lifter maintain an upright torso while catching the bar and also allows for a deeper squat under the bar. The soles of the shoes are also quit rigid, helping to resist compression while under heavy loads. These firm soles also allow the even distribution of load onto the platform, thereby maximizing the lifters force. The shoes are designed for maximum stability while remaining flexible in the toebox. This allows the lifter to come up on their toes and catch the weight on the ball of their back foot during the jerk movement of their lift.
