I altered my Touring shoes to work well with my traditional toe clip pedals , to have some float, and fit my feet loosely with room for a comfortable Insole.
so the circulation of 'my humors' to my feet, was better. and the toe strap and the slot inthe shoe sole Kept my foot on the pedal with out a tight shoe..
Which with clipless systems, snug shoes seem needed , or you pull your foot out of the shoe too easily ..
I have SPuD pedals, Shoes, and a pair of Sandals .. just havent used them on my long tours . which I did at a rather relaxed pace, any way..
