You proberbly had one of the other models like the esk brass neck ,,, the Tay sport are ok ,, but feck there heavy,, they also wear on the inside on the heel to the extent it wears through to the rubber,, then that's starts to give you blisters on the heel.
I've just got some aigle parcours iso,,,, ten times lighter and ten times more comfy than the Tay ,,, but even these are feckers for walking on slope, as your ankles go over,,, boots far better
