I purchased two pair of these shoes one for myself and one for my mother.  I wore my shoes twice, and she wore hers I think three times.  One of my shoes came loose while and work and both of hers came loose. I got in touch with the company to let them know what had happened and as of yet not a good answer back from them. I didn't ask for a refund just another pair of shoes, and we both have our shoes to return  It's a good thing I didn't put too much money into the shoes, because I dont think the company is going to make good.
