Just getting back into Cycling. Purchased my first road bike since I was a kid. Found a 06 Trek Pilot 2.1 63cm on sale for $1000. Trouble I am having is finding shoes that fit. I wear size 16 us and my feet are narrow/flat. I purchased a pair of of Sidi Bullets in a 50. Width wise they are fine but I could use little more length. Anybody know of any shoes larger then a 50 that won't break the bank?
