This was my second order. I typically wear a size 7 and purchased the 6-7 sandal; they were too small. Returned and purchased these in the 8-9 size. I would have been able to work with the bit of extra length, unfortunately, the space between the top of my foot and the straps was so large that my entire hand could easily fit on top of my foot/beneath the straps. At the high cost to return, I will not be trying again to see if this was a quality mishap or if all Indosole shoes are this far off from the industry standard.
