Re tighten the working screw a little to straighten the cleat and share the load. Remove the laces (or undo the straps) pull the shoe tongue to one side and slide the shoe over an end-up house brick. Use an impact driver with a hex bit. (You know how to use one, right? You start to use it like a normal screwdriver - then while holding it twisted tight against the resisting screw - you belt it on the top with a hammer) This has never failed me - although Time now use hex heads that are too small for my impact driver hex bit. I think I shall have to Dremel a flat blade slot in the heads of the next ones.

Anyhow - Impact Driver.

(by the way - Screw Extractors are often called Easyouts - this is only because ExtremelyFriggingDifficultOuts won't fit on the box)
