An upper is provided for a shoe. The upper is basically provided with a base layer, a first reinforcement layer and a second reinforcement layer. The base layer includes a toe portion and a heel portion. The base layer has a joint free three-dimensional shape at least partly defining an interior foot receiving space. The first reinforcement layer is disposed on an outer side of a centerline of a toe-heel direction of the upper. The first reinforcement layer overlies a first heel area of the heel portion. The second reinforcement layer is disposed on an inner side of the centerline. The second reinforcement layer overlies a second heel area of the heel portion. The first reinforcement layer and the second reinforcement layer are separated at the heel portion.
