Shoe

A shoe, comprising:

• a front portion including a front sole and a front upper, the front upper being attached to the front sole and extending over the front sole and configured to extend over a foot of a wearer;
• a rear portion attached to the front portion, the rear portion having a rear sole and a rear upper attached to the rear sole, the rear upper and the rear sole configured to support a heel of the wearer, the rear sole having a bendable portion and a rear heel portion, the bendable portion being resilient and bendable from a relaxed position to a bent position so that the rear sole is bent relative to the front sole, the bendable portion being in a biased condition when in the bent position so that the bendable portion is biased toward the relaxed position when in the bent position;
• and
• a first coupling element extending between the front portion and the rear portion, the first coupling element having a first part and a second part, the first part coupled to the rear portion and the second part coupled to the front portion, the first part and the second part sliding relative to one another when the rear sole moves from the relaxed position to the bent position, the first part and the second part automatically being in a locked position which prevents further relative sliding between the first part and the second part when the rear sole is in the bent position, the locked position being overcome when the wearer steps onto at least one of the front sole and the rear sole.
