The Gabby Sneaker (Women)

My feet are the exact same size and a true 11 (I go up to 11.5 or even 12 for running shoes). When I put on the first shoe, it fit good and was comfortable. The toe box room was more for running than walking but I would not have been able to drop to a 10.5 even if it existed. Then I put on the second shoe and it was just slightly larger enough to really cause problems. The heel slipped and also dug in when I walked. Comparing the two shoes, the length is the same, width matches on the bottom, but the heel cups on the back one shoe is ever so slightly larger and taller. There are no sizes marked directly on the shoe to confirm whether they are both the same size and width. Sending them back to the vendor I got them from. Pretty disappointed because if this is “allowable tolerance” I could be playing shoe whack-a-mole to find a pair that is correct size and both matched. I’ve owned 3 pairs of voinic sneakers and countless sandals and shoes and never had this issue (although their 11 does tend to run SLIGHTLY large compared to other brands but generally works).
