This may sound like a completely ridiculous question but i just received my info from the Para POC and have been trying to get through to them on the phone all morning. It states I need some "rubber soled boots with a heel block". Would the sort of thing that I'm looking for be available from an army surplus shop or is there somewhere else somebody could recommend I purchase these boots from or is there any certain type I should be looking at? Also for anybody who has done the POC. Whatâs the 1.5 mile course like? flat? laps? Thank you. Charles.
