Shoes should fit comfortably and supportively, neither too tight nor too loose. Here are the key points for proper shoe fit:

• There should be about 3/8" to 1/2" (roughly the width of a finger) of space between your longest toe (often the second toe) and the front of the shoe to allow for natural foot expansion and movement

• The shoe's shape should closely match the shape of your foot, especially in the toe box area, which should be wide and deep enough to accommodate your toes without squeezing or rubbing. This prevents issues like calluses or sores

• The heel should fit snugly without slipping or sliding when you walk, providing good support and stability

• The ball of your foot, the widest part, should align with the widest part of the shoe to ensure proper width fit

• Shoes should feel snug around the midfoot and heel but allow a little wiggle room for toes to move comfortably

• Try shoes on both feet and choose the size that fits the larger foot for best comfort

• Don’t expect shoes to stretch significantly over time; they should fit well at the time of purchase

• For running shoes, it is often recommended to buy a half size larger than your normal shoe size to accommodate foot swelling during runs

• A simple test to check fit is to stand and walk in the shoes to ensure no chafing, rubbing, or slipping occurs

In summary, well-fitting shoes provide enough length and width room, secure heel fit, and comfort without pressure points, ensuring foot health and comfort during wear.
