Our Base Pad Shoes shore up your RVs foundation with a jack pad that stays put. No more storing pads with dirt and mud on them in your RV or tow vehicle. Our molded rubber shoe is not glued together crumb rubber but an EPDM molded product design to protect your equipment while adding stability once parked and leveled. Once installed it stays on. It can be removed and re-installed if necessary as many times as you need to.
