In an embodiment, an exoskeleton that can be applied to a limb of a wearer (P) includes a first member (12) and a second member (14) with an articulation (16) set in between to enable a relative movement of angular orientation of the first member (12) and of the second member (14) over a range of angular orientation. The exoskeleton (10) can likewise present at least one of the following features: - i) the second member (14) includes: - a first structure (14a), which can be oriented at the aforesaid articulation (16) with respect to the first member (12) over the entire said range of angular orientation and - a second structure (14b), which can be coupled to the limb of the wearer (P) with a latch device (20) for latching the second structure (14b) to the first structure (14a), the latch device (20) being selectively disengageable at a certain angular position of the aforesaid range of angular orientation to render the first structure (14a) orientable with respect to the first member (14) independently of the second structure (14b) and/or - ii) the exoskeleton includes a distal end platform (22) coupled to the exoskeleton via a ball joint (18).
