I believe they wear there own as mentioned above. Our class and those before us did not. It was one of the major items we complained to leadership about when we were getting ready to take over as detailers When I ran detail they allowed Plebes to wear their own running shoes for PEP, have Gatorade at every meal, and anti-bacterial soap as part of the issued gear. Believe it or not, these three things were game changers. Allowing Plebes to run in their own "go fasters" cut down on shin splints like no tomorrow. Lets face it, no way one shoe is going to work for 1200 people. Gatorade helped reduce heat injuries by over 50%. Plebes drink so much water and sweat so much, but replacing those electrolytes and all those other fancy things help unbelievably. We were issued ivory soap when I was a plebe, but with as much as you sweat Plebe Summer, your skin grows some pretty unique things. The addition of anti-bacterial soap helped cut down on heat rash and all kinds of other fun things a great deal. Its amazing the small changes can make to keep people healthy and in training.
