Abstract: An athletic shoe has a shoe portion with a sole having a number of projections extending from the sole. A detachable sole with a number of cleats or the like extending therefrom has grooves designed to mate with the projections on the sole of the shoe. Each of the projections and grooves have tapered edges such that the detachable sole will only be released from the sole of the shoe when a specified force is applied across the width of the shoe. In addition, the projections may have notches along their edges which mate with projections extending into the grooves on the detachable sole to facilitate the holding of the detachable sole on the sole of the shoe.

Abstract: A shoe construction is described for improving the posture of the wearer, as well as reducing the wear on the rearward edge of the heel, without substantially changing the exterior appearance from conventional shoes. This is accomplished by hollowing out a portion of the top of the sole portion, particularly in the heel region, so that the sole of the wearer is inclined upwardly toward the toe portion of the sole at an angle of about 2.degree.-10.degree.. The shoe upper is substantially conventional; however, to comfortably accommodate the ankle of the wearer, due to the lowered heel, the rearward edge of the shoe upper is lowered an equivalent amount. The development is illustrated for shoes having a separate heel portion as well as for wedge-type shoes.

Abstract: This invention relates to an ice hockey shoe with an outer shell of a relatively hard synthetic resin and an inner shoe made of a relatively soft synthetic resin, and with a blade support attached to the outer sole.

Abstract: A shoe of the sneaker type. This sneaker is provided with a shoelace or shoe string having branch strings or with a plural number of strings so that said string or strings may be tightened across the instep at a plural number of spots on the shoe. By this, the shoe can be tightened for fitting by the wearer without taking the trouble of adjusting the string as in the case of conventional sneakers.
