If these shoes were any lighter you'd swear they forgot to put them in the box.It isn't often that a pair of shoes comes along that makes you forget you have them on. That is until you take them off at the end of the day and immediately put them back on. Sperry's Gamefish 3-Eye Boat Shoes are that comfortable. Purpose-built with your waterlife needs in mind, these shoes have more going for them than their obvious good looks. Keep reading and we'll let you in on the secrets behind their mastery of all things in, on and around the water. Imported.The Uppers: Their premium nubuck and full-grain leather uppers feature handsewn construction for durability and a luxurious look and feel.

And since they run the length of the shoes, these cushioned midsoles provide all-day, under-foot shock absorption.SON-R Technology: This patented system features a unique outsole design that works in combination with an interactive footbed to provide natural sensory feedback and awareness for greater stability and agility on multiple surfaces. This design enhances proprioception (the unconscious perception of movement and spacial orientation), effectively giving you the ability to See With Your Feet. Articulating outsole pods transfer sensitive information from whatever surface you're on to corresponding pods in the removable, interactive, compression-molded EVA footbeds and then to your
