With the protection of a shoe and the breathability of a sandal, 'Greyson' from Josef Seibel is an ideal choice for warmer weather. Rich leather or nubuck upper with adjustable hook-and-loop instep and ankle straps for a secure fit. Leather-lined Air Ped insole gently massages the foot with small nubs and is contoured for proper support. Lightweight but very durable synthetic outsole absorbs shock and provides sure traction.
