Kayanos are for distance walking or casual jogging, not for sprinting or anything that requires abrupt changes of direction. If you need to do a lot of walking or are in a friendly marathon that you want to merely participate in and not dominate, these are as good as it gets with unusually light weight, a very comfortable step that borders on cushy, and a velvety sock liner that makes cheap/no socks feel expensive.
I don't know if you know my backstory, but I work in an Amazon Fulfillment Center, a warehouse where everything that you see on Amazon is physically stored; I walk between 12-15 miles a day and manage an even 3000 miles per year, so comfortable shoes that last are not optional. I've been wearing Kayanos for over three years and own at least one pair of every version since version 20. A bit of water and a brush every so often and the shoes look pretty much the same as new, after ~3000 miles the interior and exterior/bottom sole show mild wear and that's it, these shoes are like alien technology compared to what's sold at the mall..
I've only put a few dozen yards on these today, but they're representative of Kayanos in general; very comfortable out of the box, I'd gladly just throw them on and then go work my shift (which I've done with new pairs before, and will do with these tomorrow.) If you don't need the oil-slick reflector bits, the standard version is ~$20 cheaper. I'd also recommend the version 22 Kayanos which you can still find for only ~$100.
