A snowboard boot and an assembly of a snowboard boot and a retention apparatus for securing the boot to a snowboard. The boot includes a sole, an upper affixed to and extending upwardly from the sole, and an attachment member attached to the sole. The attachment member has a portion extending substantially longitudinally and spaced from a portion of the sole for facilitating engagement with a latch of the retention apparatus. The retention apparatus of the assembly includes an attachment mechanism for attaching in a vertical direction and along a horizontal plane, which cooperates with a complementary attachment mechanism of the boot, arranged in a central portion of the sole of the boot. The boot includes a skeleton that is constituted by a minimal force-transmission circuit which provides for the support necessary for practicing the gliding sport and the force-transmission circuit passes through the attachment mechanism of the boot. The integration of the boot having a minimal force-transmission circuit and its direct linkage with the attachment mechanism of the boot make it possible to ensure a good transmission of forces and support for a minimum space requirement of the retention apparatus.
