The Challanger ATR Trainers brought to you byhokaworks a combination of durable waterproofing and optimised breathability. Sometimes it's hard to stay dry without developing that distracting clammy feeling, but GORE-TEX keeps water on the outside while letting perspiration escape from the inside; keeping sweat to a minimum and you, cool and comfy. Surrounding the upper of the Challenger ATR 6 is an extremely breathable mesh, which will work to keep you feeling ventilated and comfortable no matter what. Air that builds up within that is warm will be able to escape out, where it is then replaced by cooler Air from outside the shoes.
