Founder isn't a disease, it's a condition where the tissue that attaches the hoof wall to the bones inside is compromised. It's generally brought about by too much rich feed causing inflammation that cuts off critical blood flow to that tissue.
Moisture and soft ground also contribute to slipperfoot in deer. The wet keeps the hoof wall soft, so it flairs . Not having any hard ground limits any wear factor, and virtually eliminates the opportunity to break any of it off. It's most common in areas where corn is grown in muck fields.
