Constructed from 100% Fluidfoam neoprene with glued and blindstitched seams, these boots feature a torsion control design and an anti-flush shin strap to keep water out. The split-toe configuration improves balance and board feel, while the durable textured outsole ensures reliable traction on slippery surfaces. Taped interior seams add durability and comfort for extended sessions in the water.
