Gravis Leather Sneakers Size 27, Black, No Box I enjoyed wearing these on my days off and when going out. They're stylish and cool, and I think they can still be used. I have other Gravis sneakers as well. It seems like this design is hard to find now. Please take a look if you'd like. Gravis is a shoe brand that was born in 1998 from the American snowboard brand Burton.
