I agree with A. Harris, these shoes will be tricky to fit well, without having them tried on first. If your instep is high, the elastic would be permanently stretched and will show between the strips of leather; if your instep is low they might be too loose and there is no way to tighten them (a stick-on tongue underlay on the instep might help). They are designed to be formal shoes, not casuals and can be worn in every situation where lace-up oxfords would be appropriate. Ferragamo shoes (at least in the States) are available in three different fittings: B, D and EE. Unlike most items of clothing where the main measurement is circumference (chest, waist, collar); in shoes, the main measurement determining size is length. If a shoe is too narrow, you might have to go up half a size, which might make them too long. Alternatively if the circumference fits but the shoes are too short you might have to go up in size but down in width. Many continental makers have stopped producing different widths. If you want to get shoes by mail order stick to a few firms whose sizing you know well and don't experiment too much. Unlike a suit where you can make alterations (within limits) with ill-fitting shoes, there is not very much you can do.
