I actually had to much room in the heel of the shoe and there was no way to adjust my foot to fit, they actually felt like flip flops. Love them and now have 4 in this style, and one other Teva sandle in another style that is also super comfortable. 1 Soundsystem hören. I am sure it is just a defect on the one I got and not a reflection as a whole. They’re still cushioned on the sole after a month of daily wear around the house. The noise cancellation works great even if you are not playing any audio and the microphones pick up your voice while cutting out the background noise and doesnt make you sound as though you were in a cave. Offers solid protection in an attractive package. I expect to wear these for several years. I will never purchase a TACO product again. Very good quality and bright red color.
