Hey nickg, I've just remembered I've got a pair of old SPD pedals available if you want them.
They aren't pretty TBH, and I've never used them, they came on a bike I recently bought but I use SPD-SL pedals on my bikes.
You can have them for free if you want them, (just cover P&P).
Check them out
HERE.
You could then get a pair of
THESE to use until you can sort some shoes out.
Apologies for all the
Wiggle links, I'm not associated with them, it's just to easy to jump on their site and find things in one go.
