１Toe

The toes do not hit,
The tread area bends properly

The weight of the body causes the foot to stretch at the toe of the shoe. For this reason, there should be about 5 to 10 mm of space (play/allowance) between the tip of the toes and the end of the shoe, although this varies from person to person.

２Arch

The arch fits snugly

The arch is an important part where muscles and ligaments overlap in layers and blood vessels and nerves are intricately intertwined. It also acts as a spring to absorb shock to the ankles, knees, hips, etc. When you stand up and put your weight on the entire sole of your foot, it is considered ideal that the arch is neither tight nor loose, but is just barely touching the shoe.

３Top Line

The top line does not hit the ankle

The topline is the opening of the shoe, and its height and how it fits the foot greatly affect the fit of the shoe. If the topline touches the outside ankle (the outside ankle of a human foot is lower than the inside ankle), even a little, friction will occur there, causing pain and making it difficult to walk, so care must be taken. On the other hand, if the topline is too low, the support for the foot will be unstable and the shoes will easily slip off.

４With (foot circumference)

The width (foot circumference) fits perfectly.
Does not compress the instep

The width is the widest and thickest part of the foot, the size around the base of the big toe and little toe. When you put on the shoes, your foot should fit correctly and the width and dimensions should fit perfectly.

５Length (foot length)

The length (foot length) fits

There are three leg lengths:

• 1. Overall foot length
• 2. Length from heel to foot (arch length)
• 3. Toe length (from the base to the tiptoe)

If the area from the heel to the forefoot does not fit properly, it can cause many injuries and fatigue, such as unnatural bending, pressure on the toes, and arch tension.

６Heel

The heel fits

The vertical curve on the back of the heel of the shoe is called the heel curve.
First, check to see if the top of the heel curve is digging into the top of the heel (around the Achilles tendon) or causing extreme pressure.
Next, with your toes on the ground, lift your heel and bend the shoe to see if your heel will follow the heel curve. If your heel floats up, try a shoe that is one size smaller. It is best to have your entire heel lightly pressed down by the shoe for stability.
