2. The frame according to claim 1, comprising a hollow box-like body having an approximately oval transverse cross-section, which is closed downward at least one region.
3. The frame according to claim 2, wherein said box-like body is closed downward at a first region, located proximate to the interspace between the first two front wheels, and proximate to a second region located proximate to the interspace between the last two rear wheels.
4. The frame according to claim 2, wherein a first wing and a second wing which face each other protrude upward above said box-like body at a third heel region.
5. The frame according to claim 4, wherein said first and second wings, which are approximately L-shaped, are mutually connected by means of an intermediate transverse plane, which is arranged approximately horizontally.
6. The frame according to claim 5, wherein a third wing protrudes upward from said transverse plane and is T-shaped and equidistant from said first and second wings.
7. The frame according to claim 6, wherein the free ends of said first, second and third wings constitute a first resting element suitable for connection to the sole of a shoe for skates arranged upward.
8. The frame according to claim 7, wherein a second resting element for connection to said sole is obtained in said frame in a fourth region that lies proximate to the metatarsus, said second resting element being constituted by a separate transverse plane that lies on the same horizontal plane as said transverse plane of said first resting element.
