New Balance WX877SB Women’s Sneakers Size 11 The update to the wildly succesful 813, the New Balance 877 retains the slipper-like feel of the previous edition but completely updates the upper with a welded application to eliminate irritation that comes from rubbing. The stretch textile upper is a fashion-forward statement perfect for the gym or boot camp, and the durable pivot point outsole assists you and offers stable ground contact as you work out. B10
