Infant shoes

1. An infant shoe comprising:

a shoe outsole having a forefoot region and an opposite heel region and defining a longitudinal axis and a transverse axis, the outsole defining a substantially arcuate shape along the longitudinal axis from a frontmost portion of the forefoot region to a rearmost portion of the heel region, and the outsole defining a substantially arcuate shape along the transverse axis from a first lateral side edge of the outsole to a second lateral side edge of the outsole; and

a shoe upper secured to the shoe outsole, the shoe upper and the shoe outsole together defining curved side surfaces that extend within a substantially continuous curved plane such that the outsole and the shoe upper together form a substantially ellipsoid shape and allow an infant wearing the shoe to roll his or her foot to either side and forward and backward without rolling over a sharp edge,

wherein a bottom surface of the shoe outsole defines a plurality of nested elliptical grooves substantially in the forefoot region, a plurality of substantially parallel curved grooves in the forefoot region, and a plurality of nested substantially circular grooves substantially in the heel region, each of the curved grooves extending substantially transverse to the longitudinal axis of the shoe outsole and intersecting at least one of the elliptical grooves, and at least some of the elliptical grooves intersecting at least some of the substantially circular grooves, and

wherein the elliptical grooves allow the forefoot region of the shoe outsole to flex in every direction when the shoe is rolled side to side along the transverse axis, the substantially parallel grooves allow the forefoot region of the shoe outsole to flex longitudinally when the shoe is rocked forward and backward along the longitudinal axis, and the substantially circular grooves allow the heel region of the shoe outsole to flex in every direction when the shoe is rolled side to side along the transverse axis.

2. The infant shoe of claim 1 , wherein the shoe upper has a top-line defining a foot access opening that extends between a toe cap portion of the shoe upper and a heel portion of the shoe upper.

3. The infant shoe of claim 2 , wherein a front edge of a forward portion of the foot access opening defines a substantially curved shape.

4. The infant shoe of claim 2 , further comprising a strap having first and second ends and positioned to extend across the foot access opening, the first end of the strap being secured to a first lateral side of the shoe upper, the second end of the strap being releasably secured to a second, opposite lateral side of the shoe upper.

5. The infant shoe of claim 1 , further comprising a heel tab extending from an upper edge of a heel portion of the shoe upper, the heel tab being configured to move between a first position for use and a second position for storage, the heel tab extending upwardly and away from the shoe upper while in its first position, and the heel tab resting substantially against the heel portion of the shoe upper while in its second position.

6. The infant shoe of claim 1 , wherein the shoe outsole comprises:

an outer member including an inner heel region; and

an inner member located in the inner heel region and including a ground contacting surface, the inner member having a relatively higher durometer than the outer member, and the inner member being positioned and dimensioned to fit under a baby's heel during use of the infant shoe.

7. The infant shoe of claim 1 , wherein the curved grooves extend to the first and second lateral side edges of the shoe outsole.

8. The infant shoe of claim 1 , wherein the shoe upper is stitched to the shoe outsole, providing a substantially seamless transition between the shoe upper and the shoe outsole.

9. The infant shoe of claim 1 , further comprising a foot bed disposed on the shoe outsole inside the infant shoe, the foot bed being compliant to conform to and exhibit the substantially arcuate shape of the shoe outsole, thereby forming a cradle for a baby's foot during use of the infant shoe.
