... Today's humans have weaker muscles and do not live in the same environment since there was no concrete or asphalt back then. It's a lot easier and safer to run barefoot on grass, soft mud, sand, etc. through a forest then it is to try and run on sidewalks, streets, or hell even treadmills in vibrums. The cons definitely outweigh the pros. It's a fad shoe that people will ultimately get tired of because they will grow tired of constantly injuring themselves...
I could not agree more: these are a passing fad. You summed it up well, so this is basically where I quit reading this thread.
The "early world" that the minimalist shoe marketing campaigns consistently refer to didn't have broken glass, rusty metal litter, hard asphalt and concrete, and all kinds of other stuff around. To underestimate that fact can end pretty badly. I hate the anecdotal stuff as much as anyone, but I will say that I played disc golf (rocks, roots, concrete tees, etc) with a friend last summer who was giving the Vibrams a try... his weekend ended early with what I think was a sesamoid fracture (no XR out on rural campsites, but I rec he wear stiff soled hiking boots, limit activity, and see a foot/ankle specialist ASAP when he got back home).
The Vibrams (much like Earth Shoes, ShapeUps, etc) are a simple trend which I would be extremely suprised to see last more than ~15yrs...
I think stilettos, spike boots, etc which cause all kinds of problems have persisted for many decades in womens' fashion is because they were a trend... which has achieved longevity since it looks very nice + sexy when done properly. "
Bunions are very common, especially in females, who, using their feet primarily for sex appeal, locomotor function being given only secondary consideration, succumb to the dictates of fashion and develop the deformity" (PW Lapidus, CORR 1960). Steel toe, non-slip work boots are the other extreme: not for looks, but very, very functional and protective... they have persisted also (and will continue to).
...The Vibrams are a trend which not only cause all kinds of foot problems... but also look fairly rediculous. Not only do they risk injury IMO, but anyone who wants to go pick up girls at the Tiki bar in Vibrams... good luck to you
In the end, footwear is a personal choice. If they want professional advice, that's a choice also. If they want to take that advice or ignore it, that's ther perogative. If a family member (avg person, ie rearfoot striker and not a highly experienced runner) asked me about minimalist shoes, I'd say if people wanna sometimes run on a safe rubber jogging track with the Vibrams (or even barefoot), go right ahead (but I'd probably walk one lap first to look for any debris on the track). If you want to run trails, pavement, beach boardwalks, etc in those glove shoes, then I'd discourage it. If you ignore the advice and do it anyways, we'll see you in the office... and I hope you find a way to enjoy your time off from your sport while you heal your fracture, laceration, stress fx, overuse tendon injury, etc.
