Sporty, lightweight and designed for speed - Aero SL is a shoe that won't hold back. Speed laces and a pull loop on the heel make getting in and out simple, and also make it easy to quickly find the perfect fit depending on the activity. For maximum fresh air circulation to the feet during warmer weather or physical exertion, a highly breathable mesh upper combines with side openings to supply air from above, while a perforated removeable air-flow insole helps air movement beneath the foot's sole. To dampen the impact from walking and jumping on hard surfaces, a thick EVA midsole provides excellent cushioning and helps to keep the shoes extremely lightweight. Below, a rubber outsole offers solid grip, providing the traction you need during high-intensity activity and on any ground conditions.
