Are you building up the arch externally or inside of the shoe?
Dont suppose you can snap a picture?
Yeh I need to find access to a treadmill so I can film it and then get some analysis done on it, just not sure its worth bothering with for a pair of US$55 shoes.
It's a shame, I do quite like them as a concept, and once I get fast enough on a track they do bounce nicely in the midsole.
I try to get some photos and post them tomorrow. I take out the insert and tape a piece of crafts' felt under the insert where the arch starts back towards the heel and run it forward until the front edge of the arch. Widthwise, it extends about a third of the way across the arch to the outside of the foot. I also extend the felt past the inside edge of the insert so it extends up the inside of the shoe when I put the insert back in. Then, I'll overlap a couple more pieces until it feels right. If I feel a hotspot (too much pressure in one spot) I remove the felt from that spot.
The easiest way to describe it is to build up the arch with felt until it feels like a tennis ball under your arch. Then, remove felt pieces until you feel an equal amount of support on the arch as on the 5th metatarsal (outside of the foot).
To test, step forward and put your weight on your forward foot with the original insert. You'll see your ankle rotate inward as your arch pronates. Once you add the felt under the arch, do the same step forward and you should pronate noticeably less. Note that it's not necessary to completely eliminate pronation. Note also that you might need more felt under one foot than the other.
In effect, you are making your own custom orthotics.
