i make handbags and the studs i use can be removed, if i mess up applying them to the bag. just takes two plyers and twisting them in oposite directions. or you could take it in the cobbler/shoe repair place and i bet they could do it, maybe for free even.
Honestly, Unless you know what you're doing, you might do more damage if you do it yourself. I'd take it to a shoe guy, they have all the tooks and are used to doing crap like this.
