## Abstract

An orthopedic walking boot for a user includes an outer sole having a substantially continuously curved lateral profile bottom walking surface, wherein a radius of curvature of the lateral walking surface varies between 10 mm and infinity, and an upper portion arranged with the outer sole to support a lower portion of the user's leg.

## Claims

### Claim 1

An orthopedic walking boot, comprising:
an upper portion having left and right side walls terminating vertically at a lowermost left and right edges, respectively;
an insole; and
an outer sole having:
a longitudinal continuous curvature along an entire length of a lower surface from a front to a back of the outer sole; and
a transverse continuous curvature extending from a left uppermost edge to a right uppermost edge and defined by two dimensions A and B, where A is an entire length of the outer sole along a bottom surface in the transverse direction that is substantially flat and substantially parallel to a ground surface when the walking boot is upright, and B is a lateral distance between the left uppermost edge and the right uppermost edge, evaluated at every longitudinal position between a heel strike area and a toe area, said transverse continuous curvature characterized by a ratio of A:B is approximately 0.63.

### Claim 2

An orthopedic walking boot, comprising:
an upper portion having left and right side walls terminating vertically at a lowermost left and right edges, respectively;
an insole; and
an outer sole having:
a longitudinal continuous curvature along an entire length of a lower surface from a front to a back of the outer sole; and
a transverse continuous curvature extending from a left uppermost edge to a right uppermost edge and defined by two dimensions A and B, where A is an entire length of the outer sole along a bottom surface in the transverse direction that is substantially flat and substantially parallel to a ground surface when the walking boot is upright, and B is a lateral distance between the left uppermost edge and the right uppermost edge, evaluated at every longitudinal position between a heel strike area and a toe area, said transverse continuous curvature characterized by a ratio of A:B that is less than 0.63.
