I had mine done at a local boot shop. Was an ok job but if I hadn't tore the boot wide open kicking Ivan's 250f, I don't think the sole would have stayed attached long enough to wear it out. The SG1 soles are DEFINITELY longer lasting, you can tell just by looking at them. Considering my luck with Alpinestars thus far, I am just going to get the whole SG1 boot next time.
I have to admit, the IMS footpegs are what chewed up teh fist set of soles. MY newer Alpinestar's soles are holding up fine with Stock CR pegs, the rest of the boot is self destructing however.
