Squatting Barefoot?

The other day I was in the gym, It didn't happen to be my leg day but I saw an older guy who was squatting and he was doing it barefoot. My immediate thought was that's disgusting do you know how much sweat is on that floor!!! Once my moment of disgust passed I wondered why is he squatting barefoot? I came home and did some googling and found a few discussions boards on the topic. 

From the discussion boards I found that alot of bodybuilders like the barefoot because it helps their stability and balance which I guess I could understand how being more grounded could help with your balance. I also found that some people found the barefoot at the gym just as gross as me and some of them would squat in socks rather than barefoot, which is better hygiene wise for sure. 

While I did find many supporters of the barefoot their were many people who suggested that if you are going to be lifting frequently go out and buy chuck taylors or lifting shoes because they are worth it. I also found that if you are truly going to be doing alot of lifting then running shoes are an absolute no no. My brother who has been lifting for awhile has shoes made for lifting he hasn't gone the chuck taylor route because he doesn't do any crazy Olympic lifting however he found that nikes that were geared towards lifting worked much better for him in the gym all around compared to his running shoes. 

This is where so research  in to journals comes in. In (THE EFFECTS OF WEIGHTLIFTING SHOES ON SQUAT KINEMATICS  Dave Fortenbaugh1, Kimitake Sato2, and J. Kyle Hitt2) they found that shoes that are made for weight lifting are best to use they help in keeping the best form while squatting.

So what am I to do? I currently have running shoes, why after reading all of this you might ask... personally I spend alot more time doing cardio and hiit intervals then I do squatting and dead lifting (I dead lift like never to rarely). If I ever feel that I am lifting more or doing much more in the weights area of the gym I may splurge on some lifting specific shoes, and I can guarantee you will never see me lifting barefoot, I'm still alittle grossed out to be honest.   

What do you think? Barefoot? Lifting shoes? Running shoes? let me know your opinions in a comment below!
