Bioworld Size Chart

SIZE GUIDE, important issues to take into account:

1.- We recommend ordering the size we usually wear; it's the easiest way to get it right.

2.- Measurements in centimeters often lead to errors. This is due to the concave shape of the foot, with an inward curve, which is where we actually support the foot. Therefore, if we trace the outline with a vertically positioned pencil, we are actually drawing a larger surface than the actual foot support area.

3.- The length measurement we offer below corresponds to the sole length. It is very important to note that the length of the appropriate size must be significantly greater than the length of the foot. When walking, the soles bend, and extra space is needed so that the toes do not go beyond the outline of the sole. This extra space should be between 0.5 centimeters and 1.5 centimeters, depending on personal preference.
