I don't even really mean this as much of a complaint, since these types of shoes have thin soles and therefore can't really have a knobby grip pattern on the bottom like other shoes can. We know they have less traction. I'm mainly just posting because it's quiet in here. :P

So yeah. Just got back from a quick trip to the grocery store in the rain. It was... a little bit of an adventure. Maybe I should get different pedals.

There are bmx/mountain bike pedals with spike-like things. Those might not be amazing for your shoes long term, but offer amazing grip

I have a combi with shimano spd on the other side, used. They are pretty expensive new
