Before you decide, make sure you are getting something that you will use on your road bike. I had SPD/Mountain shoes and when I used them on my road bike I clearly felt like they were not working for me. The shoes had too much give in the sole and I found that I had a much higher transfer of power when I went with road shoes.

If you are looking for comfortable shoes for a touring ride you may not end up liking them for a road bike. Perhaps it's better/cheaper to use a wide platform for the touring in regular shoes and save the $$ investment for the road bike shoe/pedals later? It's just something to consider.

(I have switched from SPD pedals on my hybrid, to Light Action on my road bike and on my Bike Friday. I use Speedplay pedal covers on the Bike Friday when I just want to tool around. But for long rides I use my SIDI's and cleat covers. More efficient and less work for the feet.)
