Best Time of Day to Try on New Shoes
Try on new shoes between 3 PM and 6 PM, when your feet are largest due to natural swelling from walking, standing, and heat-up to 8% bigger than in the morning. This guarantees a fit that prevents pinched toes and blisters during daily wear. Always wear the socks you normally run in, walk on hard floors, and check for snug heel lock and a thumb’s width of space at the toe. Pick the right size now, and you’ll avoid discomfort later.

Notable Insights
- Feet are largest between 3 PM and 6 PM, making this the optimal time for accurate shoe fitting.
- Foot size increases up to 8% by late afternoon due to daily activity and gravity-induced swelling.
- Morning fittings may result in tight shoes, as feet are at their smallest size around 7 AM.
- If trying shoes earlier, add 1/8 to 1/4 inch of toe space to account for afternoon expansion.
- Re-measure foot size every few years, as aging, weight changes, or pregnancy can alter foot dimensions.
Why Afternoon Fittings Prevent Tight Shoes
Even though you might feel tempted to grab a new pair of shoes first thing in the morning, your feet are actually at their smallest then-meaning you’d risk buying a size that’s too tight for daily wear. Later in the day, your feet swell from activity and gravity, increasing up to 8% by the end of the day. That’s why the best time to try on shoes is between 3 PM and 6 PM, when your feet are at their largest. When you try shoes then, they’re more likely to fit correctly during real-world use. Proper foot sizing supports long-term foot health, prevents blisters, and improves comfort. If shoes fit at the end of the day, they’ll fit well anytime. Studies confirm peak foot volume happens in the afternoon, making this time of day the most reliable. Choosing the right size guarantees your shoes will fit, mile after mile.
How Daily Swelling Changes Your Foot Size
Why do your shoes feel tighter by evening? Because your foot swells throughout the day. As you walk and stand, fluid pools in your lower limbs, increasing foot size. In fact, swelling can make your foot up to 8% larger by late afternoon. Heat and activity make it worse, spreading your foot wider and pushing your toe toward the end of the shoe. This daily swelling means your fit changes-it’s not your shoe shrinking, it’s your foot expanding. For the best fit, try on shoes when your foot is at its largest.
| Time of Day | Foot Size Change |
|---|---|
| 7 AM | Smallest size |
| 10 AM | Slight swelling |
| 1 PM | Moderate increase |
| 4 PM | Noticeable swell |
| 6 PM | Peak swelling |
Trying at peak swelling guarantees comfortable all-day wear and prevents painful constriction.
How to Compensate for Off-Hour Fittings
If you’re stuck trying on shoes before your feet hit peak swelling, plan ahead by adding a little extra space-about 1/8 to 1/4 inch-at the toe to offset the 5–10% increase in foot length that typically happens by late afternoon. To find shoes that fit accurately, wear the same socks you’d use when wearing shoes daily; this mimics real conditions and helps you buy shoes closer to your correct shoe size. Walk at least five minutes on hard flooring to check the fit as your feet shift and expand. Use a Brannock device at home in the evening to know your true size that fits, then compare when shopping earlier. Focus on a snug midfoot and locked-down heel-even if the new pair feels roomy now, your new shoes will stretch. Prioritizing these details guarantees every pair of shoes supports you all day.
When Life Changes Mean You Need a New Size
Your foot size isn’t set in stone, and counting on the same measurement for years can lead to blisters, pinch points, and long-term discomfort, especially as life throws changes your way. You might not realize it, but aging, pregnancy, weight gain, or health issues like edema can shift your size-sometimes by half a size or more. Ligaments loosen, arches flatten, and one foot may even grow larger than the other. That’s why re-measuring every few years is smart foot care. When buying shoes, always find ones that match your current shape-especially if you’ve developed bunions or hammertoes. Skipping this step risks foot problems and shoes that don’t fit properly. The right shoes make all the difference, so take time to find the new size your feet actually need. When shoes fit, you move better, longer, with real confidence and comfort.
On a final note
You’ll get the best fit if you try on shoes in the afternoon, when your feet are naturally swollen from daily activity. Most runners need at least a thumb’s width of space in the toe box, especially in models like Brooks Ghost or Hoka Clifton. Morning fittings often lead to tight shoes by evening. If you must shop early, size up, wear your typical running socks, and walk on a treadmill to test comfort.
