My experience is that slipping is primarily a function of ground surface and tread. Different Go Walks (and imitators) have different treads. Some start with more tread depth than others, and the longer you wear the shoe, the more the tread wears down. I average 250-300 miles per month including a lot of force on hard surfaces, so tread wear becomes significant after a few months. If I wear the shoe for enough months, the tread becomes almost completely flat, result in slipping if not careful.
Even with new treads, muddy type surfaces can be challenging, even more so ice. If you are planning to walk through a good amount of mud/muck/ice, I’d choose another type of footware. In addition to slipping, the water gets through the mesh holes, making socks damp.
