Earth's topography has nothing on the Adidas Terrex Free Hiker C.RDY Shoes. These waterproof hiking boots could surely traverse the extraterrestrial lands of undiscovered planets, but for now, the Continental™ rubber outsole will keep you grounded as you navigate muddy trails and slushy slopes. The BOOST midsole doesn't exactly qualify these as bouncing moon boots, but it sure does give you that extra push when you're moving through rough terrain for miles on end. They're sealed with GORE-TEX and cushioned with an EVA stabilization frame so nothing can stand in your way. And hey, if you ever do embark on a mission to outer space, you can immediately check 'footwear' off the packing list.
