Those include the price of the deal, Foot Locker’s struggles amid Dick’s market-share gains, competition, potential regulatory scrutiny

Dick’s Sporting Goods is buying the struggling footwear chain Foot Locker for about $2.4 billion, the second buyout of a major footwear company this year as business leaders struggle with U.S.

Together, the two retailers will have to wade the choppy waters of new tariffs on imports, including footwear. And they'll face the growing competition from shoe brands selling directly to shoppers.
