Follow the recommendations, buy them a little more than you usually buy - lasted 11.5 (I take 11) and they fit perfectly. They look a bit chunkier on the midsole (which is straight, a lot of walking shoes have grooves) but otherwise they are aesthetically beautiful and perfect for running up and down hills in Scotland, which is what I used them for! Not sure if they will wear well in very very cold temperatures but as I doubt I will be using them for glacier hiking I would happily recommend them for now!
