I got a pair of Palladium boots in Khaki, and they were too small, in my size 11. I got returned them and got them in 11 1/2 and they fit great. Then I these in 11 1/2 and they're too small, and I'll have to return them and get ... 12? It's clearly a guessing game and more effort than I want to spend on shoes with inaccurate sizing.
