The Realm Pull is a very good take on a popular design. Full-grain uppers and a very light weight, sticky sole (which I am told is re-soleable,)make a very comfortable boot. I wear a 10.5 and the pair of Realm Pulls I got fit very well. There is adequate room in the toe box. As is common in most pull-on boots, the heel is roomy. There is also just a little bit of heel slide vertically. But that is a trait of most pull-boots. Mine were very comfortable right out of the box. I was surprised by the lightness of the boots. But they are very well made and I expect them to prove to be very durable. If you like the fit and comfort of Merrell's casual shoes and boots, you will be in good company with the Realm Pull. I have had many different brands of pull-on's both Australian and US. I have found the sizing and foot shape in several of the much more expensive Aussy boots to be problematic. The Realm does not share this problem for US buyers.
