anywhere really, a lot of people seem to really like superfeet. Superfeet Premium Insoles

Make sure you get the right color though, different colors are for different feet. If you have a running store nearby or a good shoe store they can usually tell you what would be best for your foot.

Cap strap isn't going to do shit to fix your problem. You need to look into insoles, such as superfeet or a-lines. If those don't work, then you may want to look into new boots. If the combination of both of those don't work, then I would look into seeing a boot fitter & having custom orthotics made up.

but you def can use the 390 straps as toe caps... and i would recommend you use them that way. i switched to a toe cap on my rome targas and would never go back
