what is the bottom of a cleat called
Cleat (shoe) Innovations in cleat technology continued to take place throughout the mid to late 20th century. In 1954, the first modern football boots were made by Adidas. They were lighter, had a non-leather sole, an upper portion made from kangaroo skin, and included replaceable rubber or plastic studs, which could be screwed in at different lengths. Later, in the 1990s, Adidas introduced another innovation in the form of rubber blades instead of studs, which faced different directions and allowed for better grip. Today, different types of cleats exist for different surfaces: replaceable aluminum cleats which are worn in wet dirt, firm plastic cleats which are for regular surfaces, and short, plastic or rubber cleats for very hard surfaces.[7]
Bicipital groove The bicipital groove (intertubercular groove, sulcus intertubercularis) is a deep groove on the humerus that separates the greater tubercle from the lesser tubercle. The bicipital groove lodges the long tendon of the biceps brachii between the tendons of the pectoralis major on the lateral lip and those of the teres major on the medial lip. It also transmits a branch of the anterior humeral circumflex artery to the shoulder-joint.
