I'm not going to pretend like I know any mom & pop stores in the area, because I dont. Considering I'm probably the NTer that reps Buffalo more than anyone else it looks bad because I'm not really into sneakers to begin with
The Walden Galleria in Cheektowaga is your best bet if your looking mall-wise. Foot Locker, Finish Line and there's another mom & pop type place that I can't recall the name of right now. They also have a big Against All Odds store.
The Boulevard Mall on Niagara Falls Boulevard has a Champs, Foot Locker and Foot Action...but they are usually poor when it comes to sneakers. I usually never get anything there when I go for friend & family sales anyway. I think UB might shuttle to and from that mall.
Boulevard Mall is maybe 15 min away from UB South...I would guess Walden is at least 20-25 minutes. I would go to the Walden first, it's the biggest retail mall the city has to offer. Some Ontario (Canadian) shoppers will make a weekend out of a trip to the Walden Galleria.
Once again, sorry I can't help you out with anything specifically in your area. Post in here if you have any more questions, though.
Have fun in Buffalo and wait til hockey season rolls around
