Vintage Adidas Seefeld Shoes Size 10 1/2 Made in Yugoslavia Ultra rare , haven't come across other pairs like them so I am Not sure what they were originally designed for but I think that they are for cross country skiing These specialty shoes that were produced by Adidas for. The would be great for display of rare Adidas shoes . The tonge ot the shoe is beginning to shoes signs of break down due to the type of material that it is composed of, some type of vinal with a layer of foam for padding. The underside of the shoes are in really great shape and I could not find any sings of excessive ware or that they have ever been used .The interior of the shoes have the original sticker with the shoe size and does not look worn at all.
