With a 100mm last the all track pro is narrow, but not too narrow. If you have a high instep or arch this boot might hurt you. The 130 flex is nice, I don't find it too stiff at all. The rubber soles are also super nice to walk in. They come with walk to ride or alpine souls, both are nice, but walk to ride soles need the adequate bindings. I take this boot all over the mountain, including the park. Never had shin bang once in this boot, not once.
