The Metro2 BUGrip is waterproof and Icebug's best-selling winter shoe - and the world's best-selling studded shoe. Why? The answer is simple. With the Metro you get the best grip on the market - and a very nice winter shoe. The 16 dynamic carbide steel studs keep you on your feet over patches of ice and you can do many long miles on asphalt without having to worry about the studs being worn out. The full zipper on the side of the shoe makes it easy to put on and the comfortable and spacious last makes winter walks a pure pleasure!
