DS (18) is on his 4th or 5th pair of Air Force Ones - the soles wear through after about 4-5 months. I get that they are really not designed for walking to school etc. He is not massively into the fashion aspect of them, just finds them v comfortable and obvs likes being the same as everyone else.
Can anyone recommend trainers with tougher soles and waterproof-ish that will last longer than AF1, and are popular with teenage boys?
