Patsy features patent pending Activ Air Technology with TMTC air bubbles injected into natural rubber outsoles that are durable and supportive for long lasting, all day comfort. A dispersion layer reduces stress on the knees and back by distributing shock evenly and effectively throughout the shoe instead of your body. The ultrasoft and luxurious NCS Natural Comfort System linings conform and shape to the foot. Dense leather fibers provide additional cushioning and its naked quality allows the foot to breathe and wick away moisture. The sealed, air-wrapped sock traps a cushion of air between layers of foam creating a pillow-like feel with every step you take. Thin elastic t-straps provide for a secure fit. Self covered wedge heel. Rubber sole.
