Shoes look great. I was hoping for some size help. A UK 11 F on the Loake Capital last fits me decently, but is snug around the top of my foot because of my high instep. An 11 UK G in the Cheaney 11028 last feels great everywhere but has minor slipping at the heel. I imagine you'd recommend sticking with a size 11, but am I going to encounter issues because of my high instep? Should I wait for wide sizes?
