The boots on the 2 "SAS" operatives were the standard issue boot for the British Forces in 2003. They are no longer issued.
Contact an army surplus store, some stores still have a few pairs, or imitation pairs.
Altho why 2 x "SAS" operatives are wearing them I will never know as they were pure crap, uncomfortable, inflexible and they killed your feet, wore mine for a week before my ex missus sent me out some decent boots from a civy company.
Oh and as for your statement about Bandies and Engineers.... Bandies are also Medics and carry out foot patrols with the rest of the boys in the Medic Role in most units.
Engineers can and do deploy with foot patrols to carry out engineering tasks on the frontline Everywhere.

A British soldier is a Soldier first and foremost, their trade comes second. If you wish to join the SAS then you need to enlist as a normal British Soldier first.
You will then need to be in your Regiment for a few years gaining experience and once you are accepted to attend Sickener 1 and you Pass it and every other test they throw at you will you be accepted into the SAS.
And even Passing those tests is not always a guarantee that you will wear the Wings, Capbadge and Beret of a SAS Trooper. You can be RTU'd at any time for anything.
Stay in school, decide what you want to do with your life and do lots more research the Military is not a Low Risk occupation, your more likely to deploy to a war zone or operational theater now than at any other time in the last 40 Years.
So prepare yourself and have that frame of mind that you will get shot at regardless of your trade! Even Apache pilots get shot at.
RAF and Royal Navy personnel are ground deploying and doing foot patrols carrying out different tasks.
