## Abstract

A sports shoe comprising a soft innerboot (2) having a cuff (5) that partially wraps around the user's leg. A semirigid collar (6) is associated with the cuff (5) and is laterally provided with first guiding seats (8a, 8b) for tabs (19a, 19b) that protrude from a semirigid body (15) associated with the innerboot (2) at least in the heel region (4), the collar (6) being connected to the body at the rear. The sports shoe allows to obtain a comfortable fit and correct movement of the user's foot during sports practice.

## Claims

### Claim 1

Sports shoe, comprising a soft innerboot having a cuff that partially wraps around the user's leg, wherein a semirigid collar is associated with said cuff and is laterally provided with first guiding seats for tabs that protrude from a semirigid body associated with said innerboot at least in the heel region, said collar being connected to said body at the rear.

### Claim 2 (depends on 1)

Shoe according to claim 1, comprising a tongue that is formed to the rear of said cuff by forming two longitudinal openings that partially affect said cuff starting from the upper end, wherein said semirigid collar partially wraps around said cuff at the upper part of the heel region so as to affect the rear and lateral parts of the leg, a central essentially V-shaped recess being formed to the rear on said collar, with the vertex arranged approximately below the point where said tongue couples to said cuff, a first protrusion and a second protrusion being adjacent to said recess and protruding, with a reduced thickness, laterally to said innerboot at said heel region so as to protect the malleoli.

### Claim 3 (depends on 2)

Shoe according to claim 2, wherein first seats are provided on said collar, above said first and second protrusions, and are constituted by a first opening and a second opening which have a preferably circular shape and are formed above the malleoli.

### Claim 4 (depends on 3)

Shoe according to claim 3, wherein said collar is provided with a first band and a second band that protrude from the upper perimetric edge of said first seats, said collar also having, to the rear, an anchoring protrusion that is preferably shaped like an inverted L in a transverse cross-section, the free end of said protrusion being arranged towards the sole of said sports shoe.

### Claim 5 (depends on 4)

Shoe according to claim 4, wherein a thinner portion is provided perimetrically to said recess of said collar and is adapted to form a depression for the accommodation of the lower perimetric edge of a reinforcement that is connected to said collar by coupling means.

### Claim 6 (depends on 4)

Shoe according to claim 4, wherein a first semirigid body is associated with said innerboot and is constituted by a mid-sole that is shaped complementarily to the sole of said innerboot, a third band protruding perimetrically from said mid-sole and wrapping around said heel region up to approximately the pre-arch region.

### Claim 7 (depends on 6)

Shoe according to claim 6, wherein at least a first tab and a second tab protrude from said third band in the opposite direction with respect to said mid-sole, said tabs being mirror-symmetrical with respect to a median plane lying longitudinally to said innerboot, said at least one first and second tabs being slidingly insertable, at their free end, at said overlying first seats provided on said collar.

### Claim 8 (depends on 7)

Shoe according to claim 7, wherein said third band is provided, at the rear, with a coupling means for said protrusion.

### Claim 9 (depends on 8)

Shoe according to claim 8, wherein a complimentarily shaped second semirigid reinforcement and protection body can be arranged at the tip region of said innerboot, said first and second bodies being preferably connected to each other and formed monolithically so as to constitute said semirigid body.
