I really like these shoes, but the sizes do come up small. I'm a UK 5 1/2 and an EE width (wider than average), so bought these in a 6. They are a very snug fit.
Although they have elastic lacing over the front of the foot and are tightened by a toggle, this is just to tighten the fit - the shoe itself does not have a front opening but goes on like a sock. Getting them on the first time was a struggle and a shoehorn would have been useful - I have long nails and they were in imminent danger as I wriggled and pulled to get the shoes on. Hopefully as the shoe takes on the shape of my foot this will get easier.
Once on they are very comfortable to walk in (although on a 2 mile walk my toes did get a little numb) and they look great. Hopefully they will stretch a bit, but I'd recommend going up a size bigger.
