I need a bit of reverse sizing help here, hoping you guys can help out. I have a pair of the Meermin Hiro double monks in UK10. I wear it on the tightest hole on the buckle nearest to the ankle, and if I push my foot forward, I can make about 2-3mm of space between my heel and the shoe. I have a bit of heel lift in this shoe, because my heels are narrow I think, but width wise up front, I wouldn't want it smaller as I have somewhat flat and wide feet. I'm now looking at a pair of Loakes in the Capital last. Should I get UK9.5F with these or stick with UK10F?
