The shoe fits great, the build-up is pretty good. I took them out for 4-miles, barefoot as always with a new pair, it's a great way to find out where they rub. Overall the shoe came in at 510g meaning the build-up cost me 135g over the basic unaltered shoe. This is a bit heavier than the lightest build-up at 490, but lighter than the heaviest at 520g.
I talked to the founder at Independence yesterday, and he is willing to offer the same service to other people that need running shoes built up. You will need a prescription from your Dr.
My advice is as well that you need to move to a built up shoe gradually, to get to the correct height, maybe even over two or three shoes. If you arrived here from a search engine and would like to contact me for advice and guidance, my email address is in my livejournal banner, please use that.
[By coincidence I just noticed that I got my first built up shoe back on April 22, in 2008. Interestingly it included a comment from mojojoey aka @wongstar. Funny how far things have come!]
