Do I need/want road bike shoes?

[OakLeaf]

I've never worn MTB shoes and I don't know how stiff they are. But years and years ago, when I got my first pair of road shoes and stopped riding in running shoes (with toe clips), my speed increased by 1.5 mph. Without doing anything else at all.

I'm very happy with the sidi mtb shoes I have and don't feel a pair of road shoes are a must-have. The only way I'd have a second pair of shoes would be different cleat types, but then that's why I chose the same pedal for every bike I own.

Road shoes will be stiffer & difficult to walk in, but, as previously mentioned, they can help your pedaling efficiency.
One difference between the types of pedals is the way the cleats mount to your shoe. Most road shoes are set up to accept a 3-bolt mounting pattern (rather than the SPD style). This can help distribute pressure from your pedal over a larger portion of the bottom of your foot. Most road pedals will also have some sort of "float" to them, which may be adjustable, depending on which model you get. The float will help avoid some joint issues & overuse injuries. Some people find that road shoes make their foot numbness worse while others find that it gets cured by switching. It's kind of like saddle choice- everyone will be a little different.
My personal favorites are Speedplays because you can clip in to either side of the pedal, but just as may people swear by Look-style pedals.

+1 for Sidi Dominators. (plus they're on sale at TE...)

I use them on my MTB and road bike, thought it was silly to spend a ton of money on a separate pair of shoes/cleats/pedals. I ride 100+ miles, no problem. And I really like being able to walk into the house with them on without trashing the floor and be able to walk without slipping when I stop at the store, etc.

There is a lot of play in SPDs as well.

uh, my Sidi's have a stiff sole. I don't see how the road shoe could be any stiffer!
