A good rule of thumb is to leave about a thumb’s width of space between the end of your longest toe and the toe of the shoe, typically around 0.5 inches (12–13 mm). This lets your toes move naturally, accommodates foot expansion during the day, and helps prevent numbness, blisters, and nail or toe deformation. What to check when trying on shoes
- Toe box room: You should be able to wiggle your toes without them feeling cramped. If your longest toe touches the end or presses tightly, the shoe is too small or too tapered.
- Width and ball area: The widest part of your foot should align with the widest part of the shoe. If the shoe pinches across the ball of the foot, try a different width or style.
- Standing test: Stand up and shift weight side to side and forward. There should be comfortable space at the front even as your foot flexes.
- Heel fit: The heel should feel secure with minimal slippage when you walk. A snug heel reduces blisters and slipping.
- Depth: Ensure there’s enough depth for your toes, especially if you have conditions like hammertoes or wide forefeet.
Tips to optimize fit
- Try shoes in the afternoon or after feet swell a bit, rather than first thing in the morning.
- Wear the socks you plan to use with the shoes when trying them on.
- If you’re between sizes, prefer the longer size or a different width rather than cramming into a shorter length.
- If the shoe is slightly long but wide, you might still be comfortable, but if it’s too long and the toe box is shallow, it’s often better to try a different model.
If you want, share what shoe type (running, walking, dress), typical size, and your foot width, and I can suggest specific fit guidelines or model features to look for.
