Abstract
A variety of plates for footwear are provided including a polyolefin resin. Sole structures and articles of footwear formed therefrom are also provided. Methods of making the polyolefin resin compositions, plates, sole structures, and articles of footwear are also provided. In some aspects, the polyolefin resin composition includes an effective amount of a polymeric resin modifier. The effective amount can be an amount effective to allow the resin composition to pass a flex test, and in particular to pass a flex test without significant change in abrasion loss. In some aspects, the resin composition also includes a clarifying agent to improve optical clarity of the plate. In some aspects, the plates include a textile disposed on one or both of a first side and the second side of the plate. The textile can provide for improved bonding of the plate to other components such as a chassis or an upper.
