Is there a metal cleat out there that can flex in the middle of the shoe ? Every pair of metal cleats I have seen are real stiff on the bottom. My younger son 2015 had foot surgery (Tarsal Colation) a little over a year ago and his feet still hurt a lot when he wears metal spikes. Right now he wears a Mizuno erupt 9 spike turf shoe, it has enough flexibility not to cause him any problems.
Basically I'm looking for a new metal cleat designed like vintage cleats Here's a few links that will show what design I'm looking for. Any Ideas ?
