发明名称 DUAL DENSITY PLASTIC CLEAT FOR FOOTWEAR
摘要 The invention relates to a removably attachable cleat for shoes, and in particular, to a removable athletic shoe cleat. The cleat has a base of a strong material (21) and an outer layer of a soft material (20) which absorbs some of the impact force when the cleat strikes a surface. Giving the base material and the outer layer material distinctively different visual appearances also provides clear indication to a user of when the outer layer has worn away and the cleat should be replaced.
