New thinner sole design for a better feel with your board. Quick Dry Lining and UltraStretch neoprene ankle panels that form an excellent fit with your wetsuit. Velcro straps across the insteps help provide a secure fit. All Infiniti boots are 100% blindstitched, which means a more watertight construction since no stitching fully penetrates through the neoprene. Back and andkle pull loop. The most durable construction for keeping the pull loop attached to the boot. Pressure bonding also means a more watertight construction, since it requires no stitching that would otherwise penetrate the neoprene and let water in.
