DS has an Under Armour store. I bought a pair of sneakers there a few years back for a very reasonable price. Not only were they on sale, but they also took off the Annual Pass 10% discount.I wish Disney Springs would get Famous Footwear or some other shoe store. My son's sneakers ripped on our last trip and we couldn't find anything for him other than Crocs.
On top of that, - at least last time I went - the outlet store mall just off WDW property has 5 or 6 major sneaker/footwear stores : Adidas, Nike, Converse, Asics, New Balance, Clarks, and ecco.
They also have a Kipling store.
The outlet mall is off-property, but just barely. It is just across I-4 from the Disney Springs area hotels/Crossroads plaza. (Visible from I-4) It is less than 3 miles from the DS Lemon parking lot, and only because the access road kinda winds around. There's also a large Publix and a number of chain eateries over that way, plus it connects to I-Drive.
