The picture isn't very good because the sun was against me, but Jack's was a local shoe store on Sunnyside Drive (which is a side street off of Forest Drive, just past Richland Mall heading towards town). The site is now either Miyo's or Leapin' Lizards -- I can't recall exactly which space it was. Growing up, we shopped for shoes in a number of places, including Gerber's at Trenholm Plaza and the shoe departments at Sears and other department stores, but I think Jack's is where we most often ended up.
I remember in particular, that Jack's was the place I got my first pair of Sebago Docksides, a shoe so comfortable that I have worn them ever since and that would be over 30 years now. In fact, that was about the only place in town I could find them. Now I either have to get them in Charleston, or order them from amazon.com (which is OK since my feet stay the same size now).
