Grippy yet stiff shoes for BMX pedals road use?

[Catrin]

I've decided to remove the Frogs from my Gunnar for this year. I love them....but for whatever reason I am much more confident in attacking hills and urban riding when I am NOT clipped in. Clipping in makes me more cautious for some reason, and that hasn't changed after 1.5 years in riding clipless. I love my Frogs and have no desire to try other pedals as I think this is about being attached to the pedal rather than the specific clipless system. I plan on moving my beloved BMX pedals (Sunringle ZuZu) from my mountain bike to my Gunnar and am considering which shoes to use with them. I know I need stiff to help prevent hot-spots - and grippy to help those pins. I might consider another set of pedals for my Gunnar, but for now I am using what I have - I love those pedals and good ones aren't inexpensive.

I've ridden many many miles on BMX pedals, back before I went clipless, and am looking forward to the return Thankfully I've done so much mountain biking with them that I finally learned how to start/stop without pedal slap - though I certainly have scars from that

I've read of some who like these Adidas Sambas for riding with toe-clips, and the reviews say they are stiff so these just might work as long as they aren't too small, and they have rubber soles. I've read multiple very positive reviews regarding using these for riding with platform pedals (AND they are affordable). Other suggestions?
