Abstract (en)
[origin: EP0875164A1] The lower shoe construction is designed especially for safety shoes. The heel includes an energy absorber (16) to protect against impulse- or mechanical shock injuries in the heel or ankle regions. The device has a stiff, elastic deformation characteristic, with a force/distance function having a steeply-rising onset and subsequently degressive form. Preferably, the energy absorbent material is an insert embedded in a soft elastic substance, especially polyurethane, used in the sole construction. The insert is hollow and made of two parts, joined together. It may be made in an injected plastic with hardness of 60-70 Shore-D, using e.g. polyamide, polypropylene and/or polyoxymethylene.
