I usually wear UK 8 or 8.5 in Crockett & Jones. I was thinking of ordering a pair of boots on the F last and wanted to inquire what sizing would be best.
I contacted Vass and they sent the insole measurements below. All my footwear measures 28cm internally.
UK 6.5 28.1 cm
UK 7 28.5cm
UK7,5 28,8 cm
UK8 29,2 cm
I was leaning towards UK 6.5, but was wondering if dropping 2.5 sizes is wise!!
