Heel-Toe is really easy when you're 6'6" with size 13 feet! 
I do it in all cars but especially the min.
Yess! You mean you've actually found an advantage of having huge feet? Woohoo! 
I'll get my 14s on the case. Guess I probably shouldn't start messing about with heel-toe and double de-clutching in my Mum's car though 
Bad enough trying to get it into 2nd in the first place.
not so much toe 'n heel as big toe little toe methinks!
I have to take issue with Jammy (well I don't really but a bit of a barny always keeps a thread moving along ) - toe 'n heel is just a refinement of double declutching. Why would you toe & heel without double declutching?
Technically you don't need to be double de-clutching to use heel and toe. You may just prefer to use on foot when a perfectly good left foot is there
But seriously, heel and toe is just a method of operating 3 pedals with 2 feet. You can use it when double de-clutching while braking, or you may just want to blip the throttle while braking and downshifting.
Both operations are very similar, just one involves [brake] shift to neutral, pivot heel to press throttle, clutch in, select gear, clutch out [/brake] and the other is [brake] clutch in, pivot heel to blip throttle, select gear, clutch out [/brake]
