Picked these "water shoes" up on sale last Friday:
adidas Climacool Boat Lace Shoes - Black | adidas US
This morning's commute ride was the first on the Renegade with these shows - appropriately in the rain, though too light to really test the water drain holes on the bottoms of the shoes.
I'm quite pleased with them. They feel great for both pedaling and walking and they stick well to the pedals on both bikes. I'm all set now for warm weather riding, with and without rain.
