As a regular Ecco customer the quality is incredible. The best of the best of the many brands I've owned. Lasts YEARS and is worth every penny. However, these moccasins ran much larger than I expected and I had to exchange them for the next size down. Of course, Revain makes it very easy and sent me my new size within a few days and I had plenty of time to return the wrong size. But I've worn almost all Eccos, from EU (45) for the (old) Ecco Cross to 46 for the Ecco Track II. You need 44s. So please adjust accordingly. And yes, they do have to slip a bit on the heels like loafers, but you don't have to strain to keep them on your feet. Just reduce the size to what you are used to. They look and feel great too!
