This is off-topic a bit but I always wondered about like, DIY making a pair of custom road shoes myself...

I have seen so many soccer shoes and track shoes from Nike at places like Ross and TJ maxx for like 30 bucks and they have stiff ass bottom sole shanks in them just like road shoes..

I wonder if just drilling holes in them and making a thread somehow for the cleat bolts would be sufficient enough to get the job done....Or if worst came to worse, just doing a complete overhaul of the soles and gluing on old soles from a pair of long discarded road cleats...
