I’ve been wearing Vibram FiveFingers for many years now. I originally started using them for running but eventually got more into lifting and have continued using them at the gym. I don’t know if I would say I notice anything better using them over a more “traditional” shoe, but they are very comfy and I can just toss them in the washer with my laundry to keep them clean which is nice. The flexibility for calf work is certainly a plus too.

The Switch 2 has a new hardware size and some software (like Labo and Ring Fit) has a physical component that is sized to the original Switch/Joy-Con. It could be referring to that.
