Okay...so I'm going to offer advice that some may find strange, and send you to a site with specific instructions so you don't get overwhelmed and buy the wrong shoes.
shoesThis site specializes in Argentine Tango shoes...BUT they have an amazing variety of split soles if you go to their sneakers selection which is an expanded version of their ballroom dance shoes selection.
DO NOT buy the Tango shoes to dance in unless you are dancing Argentine.
Why I suggest this site. When in Buenos Aires I discovered this shoe mecca. They make all of the shoes there and they can custom design and create any shoe to your liking. If you have weird foot issues they will build the shoe to your foot for no extra cost. They are honest and they are fast.
The pretty heels are great for streetwear and they are great for dancing ARgentine but they are not designed for ballroom even though they will put on a sueded sole. Trust me I have 9 pairs of these shoes and I don't buy shoes at stores anymore (with the exception of regular ballroom shoes). I mean at these prices why would anyone buy shoes not cobbled for their foot? It is an amazing luxury and they really last. They are wonderful. So at least look in their ballroom selection. You may find something you like.
The clothes selection is mediocre, so unless you have to have harem pants which really are hot on the Tango scene I would buy my pants elsewhere.
