An supinated or under pronating foot is sometimes referred to as a “rigid lever” because it provides the firm base that pushes us forward after our heel leaves the ground and our weight shifts to the forefoot in the toe off phase of gait. This is usually quite an efficient lever for running. A certain amount of rigidity is necessary to generate the force needed to run, but too much can decrease the foot’s ability to absorb impact and, therefore, can lead to impact-related injuries. Runners with high arches tend to “over-supinate” or “under-pronate.” Runners with a supinated foot type may experience ankle pain. The most severe over-supinators tend to have a history of recurrent ankle sprains and/or stress fractures. Runners who supinate excessively require the highest level of cushioning in their running shoes and should avoid shoes with stability features. See our running shoe guide for more information.

Our clinicians see many patients with a rigid or under pronating foot type. Whilst this is generally the best of the foot types to have, due to its rigid nature, shock absorbency is poor. Therefore we recommend trainers with as much shock absorbency as possible. Luckily the leading manufacturers provide excellent shock absorbing running shoes.
