The 661 Stingers are shoes designed for serious mountain bikers. The uppers are made from synthetic leather and there's mesh over the toes and around the sides to provide good airflow and help keep your feet cool in summer.
Three simple velcro straps keep the shoes secure and allow a lot of adjustment if you've got wide feet. The toe and heel areas feature extra material to protect against rock strikes, the sole flexes just enough to appeal to casual riders and it has a great mud-shedding, minimalist design. The shoes are well made, comfortable and the price is good for the quality.
