When looking at a pair of Salomon running shoes, most likely you will be taking them trail running and if you have run on trails before you know they can have a lot of puddles, streams, or other small obstacles that you will not find on a paved road. That is why when looking at purchasing a pair of Salomon running shoes, having a waterproof pair is always a smart option as it will provide your shoes with the extra protection and help you to feel comfortable without any irritations from leaked water that penetrates the shoes.
