I followed the other reviewers and bought a much larger size than I would have otherwise--I wear a 6 or 6.5 in regular shoes and a 7.5 in most running shoes so I bought an 8 and they fit perfectly. I have some knee issues that have kept me from doing Zumba and these shoes have all but eliminated the problem because they give support where I need it and allow much easier lateral movement than many other dance shoes. I love them!!!!!
