Abstract: A shoe sole includes a chamber defined in an underside of the heel portion and an air-permeable member is received in the chamber. An air escaping area including a plurality of passages is defined in the underside of the body and communicates with the chamber. A plurality of holes are defined through a top of the boy and communicate with the air escaping area. A bottom piece is attached to the underside of the body and cover the air escaping area and the chamber. The sole is made by way of molding and by foam material.

Abstract: A shoe sole includes a sole body having a shock absorbing unit integrally connected to a recess in the sole body and a fabric is attached to the sole body. The shock absorbing unit extends from a hole defined through the fabric. The buttering unit includes a bladder in which the elastic Polyurethane is received and a flange extends from a periphery of the bladder so as to be engaged with the recess in the sole body.

Abstract: A shoe sole includes a body made of Polyurethane and a bladder is integrally connected to the body by molding. An inlet tube and an outlet tube are respectively connected to the bladder. The bladder, the inlet tube and the outlet tube are put in the mold assembly and the Polyurethane is ejected into the concavity to form a one-piece sole with the bladder.

Abstract: An optical magnifying device includes a frame which is connected to a cellular phone and a magnifying plate is connected to the frame. The frame is able to be slid or pivoted relative to the body of the cellular phone so that the magnifying plate is moved to the buttons or the screen of the cellular phone.

Abstract: An optical device for electronic products includes at least one transparent plate which has a convex surface on a first side of the at least one transparent plate and a flat surface on the other side of the at least one transparent plate. The flat side of the at least one transparent plate is adhered to the electronic products so as to magnify words, numbers or patterns on the electronic products. The flat side of the at least one transparent plate may also be adhered to a casing having apertures, the electronic product is received in the casing so that the words, numbers or patterns on the electronic products is magnified via the aperture and the transparent plate.
