I liked these at first. I have been wearing Vionic Tide II (spring through fall) and the Orthaheel Dr Weil Flores Mules (fall thru early spring) for FIVE YEARS. These two Vionic/Orthaheel shoes have saved me from plantar fasciitis. I work from home, so shoe style does not matter, but being able to walk, does. Because I wear orthotic shoes at home, I can walk without pain, and I am free to wear whatever shoes I want when I am away from home!  It's amazing.

I decided to branch out and try a new style of Vionics since the Dr Weil Flores are no longer made. I went with these, and a size 7.5 B fit perfectly. (I wore a 7B in the Flores.)  These were fine for about 3 weeks. Then, the plantar fasciitis started returning. I quickly changed back into my other shoes and began my at-home exercises again. The combo was my only relief. After two weeks, I tried these Arbor Black Mules again, but still, they cause pain.  I will only be able to wear these sporadically, sadly.

What is different, I do not know, but they do not work for me long-term.
