Claims

1. An inner boot for a sports shoe, comprising: a front portion, suitable to cover toes and part of a forefoot of a user; a rear portion, that extends at a region of a plantar's arch up to a heel of the user; and at least one bellows interconnection means for connecting said front portion to said rear portion, said at least one bellows interconnection means having, in a rest position, a maximum elongation thereof.

2. The inner boot of claim 1, wherein said at least one bellows interconnection means is constituted by a bellows band having, in a rest position, a maximum elongation thereof, the maximum elongation being reducible under a compression in a transverse direction of said bellows band, thereby to compact the bellows band upon itself.

3. The inner boot of claim 1, wherein said front portion has an open box-like shape and is constituted by a first bottom having a first front curved portion provided with a front covering element that protrudes from the curved portion, with the exception of a first rear straight portion, said first covering element of an arcuate profile having, on a perimetral border thereof opposite to the front portion, an opening having two first flaps, said rear portion comprising a second bottom, with a perimetral border having a second front straight portion and a second rear portion provided with a second covering element protruding therefrom, said second covering element being upwardly and forwardly open to define two second flaps substantially mutually parallel and spaced, said first vertical borders of said second flaps facing, in use, towards said first flaps of said first covering element, being provided with two seats having an axial extension towards an inside part of said inner boot, said two seats extending along said first vertical borders for substantially their entire height.

4. The inner boot of claim 3, wherein said bellows band is folded in a substantially U-shaped configuration to define a substantially flat base connected, at longitudinal ends thereof, respectively to said first rear portion of said first bottom and to said second front portion of said second bottom.

5. The inner boot of claim 4, comprising two wings provided substantially perpendicularly to said base and connected, respectively, to an external perimetral border of said two seats of said second flaps and to the second vertical borders of said first covering element.

6. The inner boot of claim 2, wherein said bellows band is made of plastic material.

7. The inner boot of claim 5, comprising two appendices that extend in the direction of said rear portion and are positioned, partially and in a slide-able manner, within said seats, said appendices being associated with or protruding from each of said second vertical borders of said first covering element.

8. The inner boot of claim 7, comprising a small tongue, made of soft material, with an end slide-ably connected to said front portion in an area adjacent said two first flaps.

9. An arch support for footwear, constituted by a front portion, by a rear portion for supporting a plantar's arch and a heel of a user and by at least one bellows interconnection means, said front portion for supporting toes of the user and part of a forefoot thereof, said at least one bellows interconnection means for providing interconnection between the front portion and the rear portion.
