Footwear specialist Christina Rodriguez says brand, color and comfort are not the only things to consider when selecting running shoes.

"It's really important to get the right fit on shoes, the right sock, in order to make it as enjoyable an experience as possible," she said. "You can't really do much as far as changing somebody's running gait, but you can do things to help improve it."

For people who need arch support, she says optimal running shoes have a wider sole.

"If you look in the midfoot area, you'll see it's a wider fit here so it supports the part of the foot that collapses in," Rodriguez advised.

She also points out there is a dense section right under the arch, it's sometimes colored/patterned differently and feels hard. You'll want to shop for that if your ankles roll inward.

"It's called a denser stability posting so anytime anyone is running, if they roll in, it's going to push them more into a neutral position," Rodriguez explained.
