Air Max 2011 Shoe is really a great running shoe.The fit runs a bit fuller in the toe box...Super comfortable and really durable. Light. The colors are dynamic. I havent purchased a Nike running shoe in years. I was blown away by this product.The Nike Air Max 2011 Women's Running Shoe improves upon its popular predecessor with an innovative, lightweight upper and a plusher fit and feel.The upper of the Air Max 2011 Women's Running Shoe features Hyperfuse, which is made of multiple materials fused together for incredibly lightweight, breathable durability and a seamless fit. Inside the shoe, a mesh inner-sleeve, or bootie, wraps around the entire foot for a plush feel and extra breathability!
