Any shoe like this usually does that on me so I just used my hands to manually stretch and soften the area up just a tiny bit, slapped a Band-Aid on and they worked perfectly as I wore them for several hours at a wedding. I would highly recommend this rack over some of the other cheaper looking and poorly constructed wire wine racks out there. I was pleased at the heavy duty connectors on this and also the strong cable that looks to last a long time. Unfortunately, the box was thrown away to return them. His feet swell as a side affect from meds. does not even fit properly. You get what you pay for, Id still order it but dont expect amazing quality. Would recommend 10/10. Barely any difference noted when turning noise cancellation on and off. Woo and they co sign on it!
