A new manufacturer of running shoes plans to use penetration marketing to enter the crowded shoe market by using both retail stores and e-commerce methods.

Direct distribution channels refer to the methods through which a company sells its products directly to consumers without intermediaries. While utilizing retail stores and e-commerce may involve direct channels, this choice does not explain the rationale behind penetration pricing, which focuses on pricing strategy rather than distribution methods.

Profit skimming involves setting high prices initially to maximize profits from early adopters before gradually lowering prices. This approach is contrary to penetration pricing, which aims to attract a large number of customers by offering lower prices, not immediate profit maximization.

Omnichannel communication encompasses a seamless integration of various marketing channels to enhance customer experience. While this strategy may complement the marketing efforts of the manufacturer, it does not directly relate to the purpose of penetration pricing, which is mainly focused on pricing to gain market presence rather than communication strategies.
