The Captain's A/O design is a new design for Sperry featuring undated and new technology. This new design is 30% lighter than the original A/O and features genuine hand-sewn, premium waterproof leather uppers. The Hydro Grip rubber on the sole creates a super sticky outsole to deliver maximum traction. Adaptive Wave-Siping disperses the water for improved traction on wet and dry surfaces. This new design also features ASV Technology in the heel that absorbs vibration and reduces shock up to 30% for improved cushioning. The 360 degree lacing system delivers comfortable, secure fit with rawhide lace and rustproof eyelets. This new design is sure to not only provide you style but will provide you comfort as well.
