Answer 1

Climbing shoes, specially the boulder ones.

They grip like crazy and are slick. You can walk a 70 degrees flat rock without slipping, easily.

Problem is that very soft sole will wear quick, so the general shoes are a harder material and a tread to help the grip, instead of relying only on expensive soft rubber (soft rubber that wears little like Vibram does cost a bit)

Also, on wet metal surface (grates on the sidewalk) slick shoes will slip no matter the rubber quality.
