Salomon XA Pro 3D Modular Trainers - Black / Asphalt / LemonThese are pretty clever. Salomons XA Pro 3D Modular Trainers combine a synthetic mesh outer shell with a moulded OrthoLite sockliner, allowing them to be worn in three ways. With those big mesh panels, the outer exoskeleton makes a prime river shoe, while that nifty inner sock works as a slipper when you get back to the campsite. Wear them both together and youve got a comfortable pair of all terrain trainers that arent afraid to get wet.
