The shoes pictured in the listing are not zero-drop (a measure of the differential between heel and toe heights). Zero drop shoes will most certainly indicate this feature and are generally confined to running shoes to minimize the injuries caused by force placed on the heel during running in traditional "drop" shoes. An all-terrain shoe such as the one shown in the listing should have some "drop" since it will be used in a variety of settings and will provide greater stability.
This is not a zero drop shoe. Almost all zero drop shoes will be found in the running category. The zero drop helps promote a mid-foot strike rather than a heel strike through a running motion. I recommend you look through the running section. We have trail and road running shoes with a zero drop. Altra, Inov8, Merrell all make running shoes with zero drop.
If you never have had a zero drop shoe you might consider starting with a shoe that has some drop, 9mm-3mm. Traditional shoes have 12mm or more heel to forefoot drop and adjusting to a lower drop usually takes time to avoid injury and strengthen the muscles.
