I have been wearing bloch dance sneakers for 10 years and love them.  I am wearing this pair to teach zumba.  Great pivot to save the knees.  They do have a split sole which is not for everyone if you do not have strong feet. Bloch shoes require you to size up 2 sizes- I wear 7 or 8 regularly but I always order a 9.5 for bloch sneakers.
