Before you fall in love with any boot, you need to stick your feet in them. Not all boots fit all people. People always talk about boots in 2-D taking into consideration length and width. There's also "volume" which is the height of the boot over your instep and then there's the shape of the boot with regard to heal cup dimensions, and lastly where the boot wants to break across your foot. Modern boots use a poly shank that is ideally designed to offer a lot of lattitude with where a boot breaks (bends) but that doesn't always match your foot.
As an example, I would love to wear Kayland boots, but I can't get them to fit my dogs. If Zamberland doesn't fit, you might also look into their boot peers which I would consider to be La Sportiva, Asolo, Kayland and definately Scarpa. All made with similar materials in similar factories with the same level of quality and traditional approach to protecting your footsies.
