I was so excited for the Kaci II's to arrive. I've worn multiple pairs of the original Kacis for the last several years and loved the look of the re-design. Unfortunately, I couldn't even wedge my foot in. No matter how I tried, I could only fit my toes in, no use using a shoe-horn, the construction is incredibly rigid. Even my partner, with size 6.5 feet couldn't fit into these size 9 shoes! So sad to be returning these.
