    Abstract: A football fabricated of a specific injection molded thermoplastic polyester elastomer is described. A tethered football practice kicking aid, comprised of a tether, stakes and the described football with holes therein through which the tether is passed is also described. The injection molded thermoplastic polyester elastomer has a flexural modulus of 117 MPa [17,000 psi], a nominal durometer hardness of 470, a melt flow rate of 5.5 g/min., a melting point at peak of endotherm of 208.degree. C. and at the extrapolated end point of 225.degree. C., a compression set after 22 hours at 70.degree. C. [158.degree. F.] 2.8 MPa [400 psi] load of 2 and a specific gravity of 2.
