I was nervous buying shoes over the Internet. But I was thrilled with the result. My shoes are beautiful and I get compliments for both appearance and uniqueness. They feel great for dancing.
Definitely do the foot tracing technique shown on the site to get the fit right. My shoes seemed too loose at first, but the truth is that I never knew what properly sized shoes are like. Normally, I buy a little small and hope the leather stretches to fit. But when it's sized right, it's comfortable from day 1: you never have to fight your shoe.
It took me a long time to decide what leathers to use. The choices can get overwhelming, and it is hard to know how it is going to look if you stray from the pictured choices. But I did my own combo and am thrilled with the result.
Note: I bought my shoes during a holiday promotion, so the price was extra good (about the same as what I would pay for non-custom shoes here), but I think Mr Tango Shoes are a good value even at the everyday price.
