Choose the silhouette for the life you actually lead. Derby or loafer for mixed days. Oxford when you want a closer, neater lace. Brogue when you want pattern. Then read the product page for leather type, sole, and sizes — do not upgrade the material in your head.
Fit using the size guide. Plan on basic care. If you want the brand look — visible stitching, British-inspired last — start at hand-stitched leather shoes.
