Measured: Shape is judged on the outline of the toe box viewed from above, not on decorative stitching or a cap.
The basics
What to know about toe shape
Toe shape decides more than how a shoe looks. It sets how much room your toes get, how long your foot reads, and how formal the shoe registers before anyone sees the rest of it. Two pumps with the same heel and material can feel a size apart. That happens when one tapers to a point and the other curves round. A taper starts behind your toes and steals width exactly where your foot is widest.
Shape is judged on the outline of the toe box, the covered space around your toes, viewed from above. Ignore stitching, caps and broguing: a cap-toe shoe still has an underlying shape. One listing can call a shoe both closed and almond. Coverage is a separate question. Closed, peep and open describe how much of the toe shows, not the outline underneath.
Read the options as a spectrum of taper. Round keeps full width to the end, almond narrows gently, pointed extends past your toes entirely, and square cuts the front flat. Peep and open toes are cut-outs layered over one of those outlines. The further the widest part of the shoe sits from the widest part of your foot, the more the shape costs you in comfort.
