The best shoes I have found by far are soccer cleats, but the turf cleats not grass. The grass cleats are great but eat up the foothold, the turf soccer cleats have little rubber grips that stick like big cleats but leave your turf fresh like wrestling shoes. I switched to soccer shoes after slipping out on a combo, even with a heal lock. Make sure whatever shoes you wear are not a plastic leather because they are more "slippery" from what I have found. A real leather, or Kangaroo leather commonly used in soccer cleats holds up to water use and grips awesome when wet.
