This document discusses the key factors in the footwear industry including types of shoes, barriers to entry, and forces affecting competition. The five main types of shoes are athletic, boot, dress/casual, dancing, and orthopedic. Barriers to entry are high due to intellectual property protections and brand identity/loyalty. Buyer power is low while supplier power is also low. Threat of substitutes is moderate except for specialized shoes. Rivalry within the highly competitive industry is high due to emphasis on branding and non-price competition between major manufacturers.
