We put extra reinforcement webbing on the inside corners where the arch strap attaches to the base — that’s where the stress is greatest. Footcups allow rafters a stable place to put their feet, leaving their hands free for paddling. Your customers will really appreciate our footcups if they raft with children because the boot’s closed end makes it impossible for a foot to slip through. The boot is stitched to raft floor material and reinforced with 1" poly webbing around the base and 1.5" webbing over the arch.
