Fragger : Thanks, maybe later
robbest : I wasn't measured for them, but my old ones are loose so I ordered half a size smaller. They 'feel' like they fit well, just the top of the back is a bit harsh.
Trevor : That would've been sensible. I wish I was.
Homer : Can't afford the posh ones
Bigfoot : My other ones were bought in 2008 so quite likely they changed the design slightly. I just thought "Footjoy, won't be a problem".
I'm going to wear my old ones until I've healed (no pun intended) then break them in with plenty of padding on me.
In the meantime will dubbin them and maybe squidge them about a bit while I'm sitting down doing nothing.
Thanks again for all the suggestions.
