The Marketplace stores don't generally carry shoes. I would try the Super Store in Union Park on East Colonial Drive or the South Goldenrod location by the Orlando International Airport. The other place to look is Sam's Club on East Colonial Drive and Goldenrod Road. You can get a one day membership free at Sam's.
They would have a limited supply and style. You can always go to walmart.com and do a search, store availability to see what is in the area.
