A skate boot assembly comprising a main skate boot member, a bladder positioned within the boot member, and an orthotic insert positioned within the bladder. The orthotic insert is formed with two downwardly extending protrusions which fit in recesses formed in a sole portion of the bladder. The bladder in turn has downwardly protruding members that define its recesses and also fit into matching recesses formed in the sole of the boot member. This arrangement properly aligns the foot with the skate blade and with the longitudinal axis of the boot assembly. Further, the bladder is formed with properly positioned relief areas to alleviate unwanted foot pressure in certain areas, and also engages the upper heel portion of the foot to properly maintain the foot in the boot assembly. Other protrusion and recess means are provided between the bladder and the boot member so as to properly position the same relative to each other.
