While walking, 90% of body weight is carried over the heel while only 10% is distributed over the front part of the foot. In order to provide additional comfort and more evenly distribute the impact on the heel sustained with each step, a silicone cushion has been added to the heel, which differentiates the foot Comfort bed from the others. Depending on the EVA sole thickness, there are two heel heights available: 4 cm and 5.7 cm.
