I bought a pair of Ryka Studio Ds about 6 years ago to do Zumba in.  There was too much traction so I used them for workout shoes at Curves instead.  They've held up, I love the look, the fit, and the comfort.  So I ordered another, updated pair.  These are different.  Although they fit well in length, the thick insole is a major issue.  My thanks to another reviewer who mentioned removing the insoles which I did.  I replaced the thick insoles  with a flat insole and my own Dr. Scholl orthotics and I think they might work now.  What the thick insole did in my case was to elevate my foot inside the shoe, decreasing the available toe box space, altering the angle at which my foot fit into the shoe, and causing the shoe to pinch the side of my foot when my feet would warm up and swell.  I couldn't wear them and I'm hoping my fix does the trick.  Another issue - the top of one of the fabric eyelets where the laces go has completely detached from the shoe.  I will lace them without it and see it that works.  If not, I will try to hand stitch it back onto the shoe.  All in all, I'm disappointed with these but I'm hoping my adaptations solve the problems.
