Time RXS First pedals

I have managed to lose my cycling shoes (don't ask...I could spit) and I'm mulling over whether to finally make the switch to road - rather than MTB - pedals when I buy some new ones.

I've stuck with my old faithful Time Atac XS MTB pedals for years because I've never really seen the need to use anything else. They're very comfy, and a helluva lot easier to get in and out of than many road pedals I've seen - and I can walk normally in MTB shoes, which is a major bonus if you ask me.

But lately I've noticed some pain in my feet (a kind of deep muscular ache in my arches, esp on the right foot) that just might be related to my choice of pedals/shoes. So I figured perhaps the bigger platform offered by a road pedal might be worth a try.

Which brings me to my question: as a long-term Time fan I'm thinking about getting some RXS First pedals - mainly because of the amount of float they offer but also cos they're relatively cheap. Does anyone have experience of these pedals? Any thoughts? I'll almost certainly be using them with Specialized shoes, as they seem to fit me better than anything else. Any compatibility/fit issues?

TIA for any pointers.
