My friend is 5'8 and weighs about 240 lbs, he's pretty overweight, so I was happy when he told me that he's started running. But the problem is that because of (I think) influencer culture, he went and bought vaporfly 3 for his first pair of running shoes and is doing every run in them.
Now it's not as if he's running far, we are talking really really slow beginner level stuff here. But should I tell him that running in them is probably a bad idea, or just let him get on with it?
