My wife and I spent last week in Warsaw. Just down the street from our hotel was a fairly upscale shopping mall. The one evening after dinner we had a look around in the mall. We observed some familiar names and many unfamiliar. There were a lot of people in the mall and many were carrying bags indicating that they had made a purchase.
With respect to footwear, Nike, Adidas, Foot Locker, and Aersoles all had stores. We also noticed a boarded up store front with what I believe was a “coming soon” announcement in Polish for a Skechers store. The logo and Skechers written in English gave it away. However, I did not see this store listed on the Skechers Store Locator website for Warsaw though two other stores where shown with a third store that is to open in June.
