With seemingly little solution to their supply-chain issues, a trade group made up of prominent footwear brands, including Nike, adidas and Sketchers, made a plea to President Donald Trump for tariff relief this week.

The chief of the German sportswear giant said unpredictability surrounding the tariffs prevented the company from issuing a full-year forecast, but he predicted a price increase for American consumers.

A trade association representing footwear producers has asked the Trump administration to consider tariff exemptions for its products, saying the levies will drive up the cost of shoes in the US and cause businesses to shutter.
