Top 100 Biomechanical Guidelines #30: External (Outer Sole) Lifts must allow for Forefoot Flexibility

I have just been give a full 3/8 lift at the bottom of my left shoe to correct for leg length discrepancy. I am finding it difficult to bend the shoe at the ball of the foot. Should a cut be placed there and if so, how deep? Thank you.
ReplyDeleteYes, standard is full thickness under the heel which is 10 mm in your case, and 1/2 that in the ball of foot, or 5 mm. You need that forward pitch to roll through the toes. You can also request that increase forefoot flexibility be built into the lift. Hope this helps. Rich
DeleteDear Sir, I would like to be able to purchase this type of shoe lift. Could you let me have a list of stockists, as I am having trouble getting hold of them. your answer above is exactly what I require. I can only find insoles which means I keep stepping out of my shoe when walking. Thank you
ReplyDeletehow do you make the cuts Rich?
