These beautiful shoes are lightweight and comfortable, I have had foot problems (not so much now that I baby my feet and am cautious about my shoes, but these have been no problem. Ive purchased at least a 2 dozen headphones over my life costing anywhere from Walmart cheaps to Sony studio monitors ( Im older so back in my day those were like the best especially if you had an analog music source) and I have to say for what I paid for these? I couldnt be happier. Hmm, where to start. I love this shoe and it is very comfortable. Im kind of scared this will roll away if I place it on a grade? I dont like the idea of $50 rolling away from me?? Theres a thick cord emerging from the strip of buttons that could be a feasible impediment, but I dont think itll really stop anything. Theyre easy to adjust. The rings according to the FAQs on Amazon UK are 3D printed brittle plastic of awful quality. Again, for less than $400, you cant go wrong. Neither my back or feet had any complaints. Its not just a slip--they come off the heel since the heel on the slipper isnt designed well enough to hold to the back of your foot.
