I got numbness in my toes. It was just the feet getting cold
Got a nice pair of Murino wool socks and overshoes for the cold days and the problem has gone!
I didn't realise just how well ventilated my shoes are, two massive mesh parts at the front don't do anything in terms of keeping you warm.
Anyway, had a bit of a clipless moment last week.
Had a little rest on a hill for a drink, took the feet out perfectly. Had my drink, had a little chat to a young boy about my bike (bless him, never seen a road bike before
), as he walked away I put the bottle back in, tried to set off I couldn't get enough power into it, to busy faffing around trying to get clipped in (which is strange, I don't normally have any problem at all!) and causally fell on my right hand side, cutting my elbow and legs!
It was a residential road so I decided instead of getting back up I'd have a little lie down
Finally got back up and no one noticed - Brilliant!
