A swimming/scuba diving fin having a blade, a shoe open at the rear, an adjustable elastic strap engageable around the heel of the scuba diver, and two buckles at opposite ends of said adjustable elastic strap connected to two opposed side walls of said shoe, where at least one said buckle has a shaped hollow body forming integrally a portion connecting to said side wall, a channel for the axial sliding of the adjustable elastic strap, and a releasable fastening clamp of the adjustable elastic strap, where such an axial sliding channel has a hole for the inlet of the adjustable elastic strap, a hole for the outlet of the adjustable elastic strap and a deflection angle of the adjustable elastic strap positioned between such an inlet hole and such an outlet hole.

In one or more embodiments, the present invention relates to a shoe that includes a sole and an upper attached to the sole, in which the upper includes an upper main body that covers the forefoot portion, a portion of the midfoot portion, and the heel portion of the wearer, and a tongue that covers a portion of the midfoot portion, the tongue is connected to the upper main body in a front end portion or in the front end portion and portions of side portions, and the front end portion of the tongue is located such that the path length from a rear end portion of the shoe is a range of 35% or more and 50% or less based on a center line passing from the rear end portion to a front end portion of the shoe. This provides a shoe that has good fittability to the foot and good contact with the foot, and that is easy to put on.

An article of footwear includes an upper having a body with a first side and a second side, and a closure system for the upper. The closure system includes a first anchoring cable loop fixed at the first side, a flap, a flap cable loop, and a lace. The flap is fixed to the second side and extends across the body to a free end at the first side. The flap has an aperture extending through the flap. A flap cable loop extends from the free end. The flap cable loop is configured to extend from the free end through the first anchoring cable loop, and from the first anchoring cable loop back to the flap and through the aperture in the flap from an inner side to an outer side of the flap. A lace extends through the looped end of the flap cable at the outer side.

An article of footwear includes an upper that has a body extending over at least a portion of a first side and a second side of the upper. A laceless fastening system includes a strap having an anchored end fixed at the second side and a distal end selectively remote from the upper. A first fastener is fixed to an outer surface of the body on the first side. The first fastener is less elastic than the body. A segmented second fastener is fixed to the inner side of the strap. The segmented second fastener includes a proximal segment and a distal segment closer to the distal end of the strap than the proximal segment and spaced apart from the proximal segment along the strap by an exposed portion of the strap. The segmented second fastener is less elastic than the strap.

An article of footwear includes a medial support member coupled to a medial portion and having a first rail, a lateral support member coupled to a lateral portion and having a second rail, a plurality of lace-receiving members disposed on and movable along the first and second rails to move the article of footwear between an open configuration and a closed configuration, a lace member extending between the plurality of first lace-receiving members and the plurality of second lace-receiving members, a grip member extending from an upper-most first lace-receiving member of the plurality of first lace-receiving members or from an upper-most second lace-receiving member of the plurality of second lace-receiving members, and a locking member configured for securing the article of footwear in the closed configuration. The locking member has a first side portion and a second side portion forming a notch therebetween configured to receive the grip member.
