This is an "it depends". If you need more float, good advice. If your knees are like mine (I have to set my shoes with forced toe-in to get my knees to track properly), this is very poor advice that had I followed it, I would have had two knee replacements decades ago.

I can ride SPD cleats but I have to crank in max toe-in for the right cleat and while it works, it is by no means "good" and far, far from "best". Black Look Delta cleats work really well for me as do the ancient slotted cleats for toeclip pedals.

I have shoes that take the slotted cleats. To make them walkable, I brought them with cleats mounted to a cobbler and had him put on tread abound them to make them walkable. Not cheap, but he did really good work and I have done nothing burt replace worn cleats in the years since. For my knees, the right shoes and cleats are a small investment. I do have to block out the "expert advice" I hear so often.
