I think people that come to a gym often forget the most important piece of equipment. Good footwear can not be overlooked. You can buy some decent workout shoes at pretty reasonable costs if you really look for them. However, the $3.00 little flip flops just make it a danger to be working out. You should buy a shoe that is not too tight or too loose. Wear them around the house awhile to allow a little breaking in, but be wary of wearing them outside and then getting on the gym's equipment. That is terrible for the gym equipment. Also, be sure the shoes you are planning to wear, have a tread to allow you traction on machines. I have seen so many people with poor footwear get anything from blisters to much worse things like sprains, strains and even a break. The best piece of equipment in any gym is good footwear.
