Bracketing heels: toe box room and heel height are two different decisions
In a heel, your weight rides forward onto the ball of the foot, so the fit landmark moves. Find the size where the ball sits squarely on the shoe's widest point and the toes beyond it lie flat, with the longest toe clear of the end when standing. A size down wedges the ball behind the wide point and forces the toes into the taper. A size up lets the foot slide forward into that same taper, which is why going up so often fails to relieve toe pressure.
That slide is the hidden trap in heel bracketing. The bigger shoe feels roomier standing still at the till, then spends the evening ramming your toes into its point as you walk. A heel grip or a half insole at the ball can hold the foot back in the larger size, but test with the grip in place, not on a promise.
The ball of the foot is the landmark
Toe shape is a geometry problem. A pointed toe on a wide forefoot will stack the smaller toes in every size the shop stocks, because the taper starts before your toes end. An almond shape buys length without the pinch, and a round toe buys the most room at the cost of the look you came for. Naming which one you are testing saves a wasted bracket: if the shape is the fault, change the shoe, not the size.
Do the test late in the day if you can. Feet are at their largest in the evening, which is also when heels get worn. A toe box that passes at ten in the morning can fail at seven at night.
Point, almond, round: shape beats size
Heel height changes how you walk, not how the shoe measures. Above the height you are trained for, your stride shortens, your knees take the work, and the shoe gets blamed for what is really a posture limit. Walk the full length of the shop or your hallway at a natural pace in each size. The right pair is the one where you stop thinking about your feet before the end of the walk, in the height you can hold for an hour of standing.

Frequently asked questions
Why do my toes hurt more in the bigger size of heels?
Because the foot slides forward as you walk and wedges into the tapered toe. Extra length only helps if the foot stays back. A ball of foot pad or heel grip that stops the slide is the test: if the bigger size still crams your toes with the foot held back, the toe shape is the problem.
Where should the ball of my foot sit in a heel?
On the widest part of the shoe, so your weight lands on the platform built for it. If the ball sits behind that point, the size is likely small. If it slides past it as you walk, the size is likely big or the shoe needs a grip to hold your foot in place.
How long should I walk in heels before deciding?
Long enough for the slide to show itself: several minutes of continuous walking, including a turn and a stop, ideally later in the day when your feet are at their largest. Standing and posing in front of a mirror tests almost nothing a heel will do to you.
Can insoles fix a pointed toe that crowds?
No. An insole lifts and shifts the foot, and in a pointed toe that usually means more pressure across the toes, not less. Insoles fix volume and slide. Toe crowding from shape needs a different toe shape.
