Simply the best shoe store in Pittsburgh.
They have the best selection I've come across and it really seems like they take pride in carrying quality shoes.
By far the best part about the store is the sales people. They're extremely helpful, and really know their stuff. When I was looking for a new pair of boots this winter I tried a few different places. Sales associates at most places are content to grab you a pair of shoes and walk away, but here they're attentive and can actually tell you about the product (and they're not the least bit pushy).
It's the kind of place where they'll remember you, and Alberto's comment is spot on: They want to make sure you're happy months after your purchase. You really don't get service like this anywhere else. Ask for David. Terrific guy.
