Going clipless and which shoes?

Shimano R107 shoes are interesting; can run SPD-SL and SPD/ATAC on the same shoe with a crabon plate under the cleat area keeping things stiff and velcro/ratchet upper and all for £80

I tried these on - the fit is peculiar with a really wide/square toe box and a massive arch/overall curve that keeps going past the ball of any human's foot.
