yes they all have insteps, they are all race boots so the insteps are lower than most boots. they are all ski boots so the relationship between one instep height versus the other is only relevant to the foot that is going inside. which means that the instep height is adaptable on all of those boots with work that can be done on the boot board, or tongue, for opening up more room, or with tongue shims or the boot board for closing down excess room.
a good idea would be a visit to a shop that carries all of these boots and try them on your foot. then the relationship between other peoples feet and the opinion of others as to the dimension of these boots will become clear.
