Rollerblades pretty much revolutionized the concept of roller skates, and now FATblades are looking to take the skating to the snow. These mini-skis, which can be worn with traditional snowboard boots are essentially a combination of skates, skis and snowboards for the feet. The designers, which are now looking to a Kickstarter campaign to bring the FATblades to the masses, say these can be used in all sorts of conditions including ice, soft snow and even heavy powder.
