cleats - Foot gait analysis & correction

Cleat wedges are used to correct foot pronation, increase proprioception and provide better stability and control whilst cycling. They are also used to indirectly alter knee angle to reduce lateral or medial knee pain associated with bad leg tracking.

cleats - Foot arch analysis and correction

Appropriate arch supports help improve the stability of feet and increase power transfer through the foot.  
Insoles help maintain a consistent foot size by controlling arch collapse which intern help reduce numbness and/or hot spots

Pelvis, knee, foot tracking analysis and correction

Preferably the knee should virtually track in a vertical line (straight up and down) and remain directly over the second toe during the pedal revolution. Poor tracking can be cause or ankle, knee or hip issues

cleats - rotational adjustment

Poor cleat position, specifically incorrect rotational placement is the leading cause cycling related knee issues. The sweet spot placement allows the foot to freely move throughout the whole pedal stroke without restriction of the pedal tension system.

cleats - fore/aft adjustment

Poor Fore/Aft cleat positioning can cause foot 'hot spots' and is main cause of cold /numb toes
