Swimming gear shop in the Twin Cities

Another option is Elsmore Aquatic. They are located in Apple Valley.  Here's their website:

I have only dealt with them at swim meets, but they have a store as well. They're good people. Between Pure Blue & Elsmore, you will find pretty much the same stuff. Pure Blue is remodeling now and to get at things you literally have to walk through their back room of inventory.  Both shops deal with competitive swimmers and they know their stuff.
