Proper leather shoes

For me I'd say that Clark's DBs are bang-on true to size. My feet are between a (UK) 9.5 and a 10 and I wear 10s. The 9.5 DBs were a tad small and my 10s are a tad big. Wallabees come up half a size too big (again, in my experience).

The suede are tighter and stiffer than the leather offerings IME.
