I bought a pair of A530 pedals knowing that a frequent "customer review" complaint is that they are "slick" on the platform side with "street" shoes.

I rode them today in a light rain, without bike shoes, and found them to be a bit slippery. I think mostly because I expected them to be.

I did a forum search for "A530 slick" and came up with three results. Non of which are any help.

Does anyone have any tricks to make them (a fairly smooth platform pedal) have a bit more grip??
