How do we walk on a ice slab?

Question

I need explanation with diagram.

Answer 1

very carefully?

Answer 2

I'm not sure what you're looking for in a diagram?  When I walk on glaciers I use crampons, basically big-spiked shoes, for traction.  Without them I'd look for places where there's more traction somehow.  Not sure if that's what you're asking for but maybe it'll help.

Answer 3

one foot in front of the other.
