Footwear can change the way we run. It can influence our:
It has been shown that barefooted people will reduce their step length, increase cadence, and have a forefoot strike, Studies have shown that footwear can increase forces in the joints:
These increases imply greater loads on the joint and could be an explanation for some injuries, such as patellofemoral pain syndrome. Common causes of patellofemoral pain syndrome are:
As peak forces go up in a joint we tend to have more activation of surrounding tissues and hence more compression and stress in a joint.
Traditional higher heeled to toe drop shoes (24 to 12) with medial posting actually increases knee flexion torque, hence increasing medial compression of the knee joint. And, the primary cause of medial knee osteoarthritis is attributed to this increase in varus torque of the knee.
There are so many injuries that can be caused by increased rotational imbalances at the hip, so you want to avoid shoes which will put you at risk of increasing this.
It is always advised to consult with a specialist to assess your lower limb biomechanics, strength and flexibility in conjunction with a footwear fitting specialists to steer you in the right direction for the best treatment and footwear.
