A biomechanical assessment is the assessment of the mechanics of a biological system; normally with the view of improving or enhancing such mechanics as to produce favourable results.
In the context of this industry the biological system is the human body and we are generally assessing the lower limb (below the hip) biomechanics; whilst noting any significant interactions with the rest of the body.
The “favourable results” we are seeking, is helping you to select the ideal footwear for your biomechanics to help avoid injury and promote a better running style so that you get the most enjoyment out of your running possible.
When you get it just right, you will run without even thinking about your body, your mechanics will “flow” and you will relax and enjoy the run; however get it wrong and even a short run can result in injuries or pain.
