I had some zeros a few years back but wondered what’s the difference with them and the sidi courier? I’m looking for a new pair of boots that come further up my legs. 

I think the courier has a different sole. I've sidi trials and Forma Boulder boots the Formas are fine and an inch taller. Best protection I had was MX boots with a commando sole fitted by a local cobbler

I have the Couriers and they work fine for me

The Courier..a.k.a Discovery is the same sole as the Zero, but they screwed on a metal toe cap (which can be removed if so desired). They are water resistant and have extra foot lever pads added....good boot...I hear they are now discontinued...
