Actually, I am not sure which non-flange silicone tips you could use that would turn the SA6s into more of a canalphone. They really are made for sound isolation, and I don't think there is a tip that can change that. Any of the typical silicone tips for canalphones have a much wider base/hole, and would be too large for the SA6 treble tubes. One possibility is the Shure Soft Flex (NOT the olive), which are gray. But they also pretty much seal off your ear, just like the foamies and flanges that fit the SA6.
So the short answer is, no, I don't believe you can hear ambient sounds with the SA6s while walking, at least not like you can with canalphones or ear buds.
