Is it worth buying specialist cycling shoes?

When riding fixed, it's well-nigh impossible to tighten and loosen straps once you;re rolling, which is what you;re meant to do with Clips and straps .

Slighty related.

The SBS system found on Northwave shoes is adjustable while riding fixed, as there is a button to loosen the strap one tooth, and a lever to tighten one tooth. I find this really handy. Carry on :)
