I purchased these shoes based off the reviews.  I wear a women's size 7 and ordered the Sansha size 8 and they fit really well.  Good arch support.  I do have some problem that I purchased them in mid August and now it's end of December I have the front sole starting to detach from the shoe.  Hoping that it's just that shoe and not a defect in the product as the shoes work great for Zumba.  I have written the actual manufacturer and am hopeful for a good response.  Other than the sole issue the shoe has been great.

Shipping was very prompt via Amazon and arrived sooner than expected.
