Loake Jack in Sand suede:
The 024 last fits big, so take 1.5 size down from your US size, i.e. US9D = UK7.5F in these. On sale at Herring Shoes at the moment, but only smaller sizes left. They're also available from other online retailers.
Skoak, I also wear an 8 in EG, but one width down from what you take, i.e.:
202: UK 8 D
82: UK 8 E
888: UK 8 E
Would you recommend I take the same sizes as you for the various Carmina lasts? My feet are average width, but I have a low arch and instep.
