A shoe includes an ergonomic insole unit, and an upper with a bottom margin connected directly to a periphery of the insole unit. The insole unit has a heel part which includes a planar bottom face, a rear upward flange extending upward from the heel part and a concave inner surface which extends gradually upward and outward from a mid part of the heel part to the upward flange. The thickness of the heel part decreases gradually from the upward flange to the mid part and thus substantially conforms to the contour of the bottom face of the wearer's heel. The ergonomic insole unit contacts and supports sufficiently all part of the wearer's heel for better distribution of the weight of the wearer.
