Only worn a handful of times, but they are just too narrow for me now after foot fusion surgery. Super clean, no wear at all on treads! Very lightweight, slip on style! Super cute! Here is the description from the Asics website: Boost your running performance with the GEL-NOOSA TRI™ 12 running shoe. With its eye-catching design, this lightweight running shoe provides a blend of comfort and support to help you meet your training goals. For a cushioned and lightweight ride, the GEL-NOOSA TRI™ 12 model features a FLYTEFOAM® midsole, which works with GEL® technology cushioning in the rearfoot for a more comfortable run. Open holes in the forefoot drain water to help keep you dry, while the airy mesh mid-foot area lets your feet breathe. The elastic laces and a pull tab on the tongue and heel make the shoe easier to take on and off, while the AHAR® heel plug helps to reduce wear in high-contact areas to extend the overall lifespan of the shoe.
