PURPOSE: To provide sports shoes easy to ware and take off by attaching lever arms on one of the flaps of the shell forming a front opening of the instep leather with one end rotatably mounted on pivots and another end engaged with the opposite flap through a teethed band. CONSTITUTION: A front opening 4 is formed by a first flap and a second flap 5 and 6 on a shell 3 of a sports shoe 2. The two fastening elements stepping over the front opening 4 are formed by a teethed band 12 and a U-shaped lever arm 7 respectively. The base 16 of the lever arm 7 is engaged with the first flap 5 through the teethed band 12. The distal ends of wings 8a, 8b of the lever arm 7 are rotatably secured on the second flap 6 through pivots 10a, 10b. When the wings 8a, 8b are outwardly turned down, the teethed band 12 is tensed and the lever arm 7 keeps tight to the instep of the foot, and when the wings 8a, 8b are turned upward, the foot can be taken out of the shoe 2. The upper part of the shoe is worn on or taken off the ankle by a securing device 1 of the same structure. Thus it is easy to wear or take off the shoe. |
