If your workout shoe doesn't fit right, then your workout won't feel right. Get a good shoe and you'll have solid footing for all of your exercise needs. What determines a good shoe? Try these six things on for size.

Anchor For Your Ankle

The area around your ankle, called the anchor collar, should be heavily padded to prevent twists and blisters.

The Deal For Your Heel

Go for a snug fit around your heel and a high Achilles notch, the slight dip at the top of the shoe's heel, to support your foot and prevent it from sliding forward.

Sole Endeavors

Make sure your outer sole is textured enough to give traction and prevent slipping. The rougher the terrain, the deeper the grooves should be.

Insole Insights

The insole of your shoe should support your arch, keep your feet and lower body in proper alignment, and help distribute your weight evenly across the bottom of your foot. When you walk, it should feel like a cushion underneath.

Wiggle Space

Allow for ¼ to ½ inch of space between your big toe and the end of the shoe to prevent calluses and provide stability. Don't forget -- your foot expands slightly as you exercise.

"Last" but not least

Your shoe should fit your arch type. If you have a high arch, look for a curved last. This means the edge of the sole noticeably dips in at the middle. For a low arch, you'll need a straight last with edges of the sole that are straight. For more on arch types, click here.
