No. Walking is dependent on "pushing off" from a surface, which
requires friction. If you've ever tried to walk on ice, or watched an
excited dog "spin out" on a waxed floor, you understand this principle.
If surfaces were frictionless we'd have to use reaction drives (jets or
rockets), as octopi and squids do.
