A ski boot comprises a sole portion (2) that is attached to one or more separate outsole elements (3, 4, 5) for location between the sole portion (2) and a ski binding. At least one of the outsole elements (3, 4, 5) is adjustably mounted on the sole portion (2) prior to a secure fixing of said outsole element (3, 4, 5) to the sole portion (2) by at least one fastener (13) so as to be adjustable in forward, rearward, lateral and medial directions relative to the sole portion (2) and so as to be rotatable clockwise and counter clockwise relative to a centerline of the boot. Preferably, at least one of the outsole elements (5) is adapted for attachment to the ski binding. Advantageously, a plurality of outsole elements (3, 4, 5) is provided that are adjustably mounted on the sole portion (2) independently of the other outsole elements.
