Size 9.5/42 baseball cleats (Curtis Bay)

Do you have some old baseball cleats that aren't good enough to play in? Or golf shoes or something similar? I have to cut a very steep hillside with a string trimmer and am trying not to hurt myself, especially if the "grass" (OK, it's really all weeds) is a little damp.

If you know of a used sporting goods store near the Glen Burnie area that might have some for cheap I'm all ears as well. The Goodwill on Ritchie Highway had some today but the largest size they had was a 9 and i could just barely cram my foot in one, that's what prompted this. Thanks!
