I find the C&J lasts to be enormous- and the 348 most ginormous of all.
I take UK 8.5 in 348 and UK 9 in the 341 and 337.
UK9 in Vass F, UK 9.5 in P2 and U.
You may be UK8 in Vass F, and maybe UK 8-8.5 in U.
I run for about half an hour, stretch, then go to bed an hour later. Steadily losing weight for 4 yrs (about 20 lbs). I have no clue about the science, but I know it seems to help me sleep, if not metabolize faster.
cheers- re: heel shapes ... the pointy toe takes a tapering-to-ground trapezoid - like a cowboy boot, or women's heels - for balance and even distribution of weight. A broad rounded-toe takes a broad heel tapering-to-top trapezoid for the same reasons.Acc to Vass a slight asymmetry in the heel is most comfortable for shoes in between. l to r: F dble; P2 pebble; F single in antic cognac, but IMO it's a very dark one. so many shoes, so little...
Great shoes above, congrats. nerd alert, Vass heel shapes- l to r from top: U last single sole, U double, F single, F double, P2 single, P2 double and just for point of comparison EG Dover Pointy lasts like U take a trapezoidal wedge shape tapering down in single, but AFAIK the rest are slightly assymetrical but identical
