Here are some shopping tips: 71 Depending on your workout, shoes designed for walking, running, tennis, cross-training or another specialty will provide the best support for your feet. Shop when you normally exercise. Feet actually get bigger throughout the day, sometimes swelling up as much as a half-size by nighttime. 72 Try them on. Never grab a pair of exercise shoes based only on the size of footwear you normally buy. Bring the type of socks you’d wear to work out and go for a walk through the store. 73 You should be able to spread your toes out comfortably. Make sure there’s about a half-inch of space between them and the front of the shoe. The back should fit snugly (warmly and comfortably) against your heel and not move up and down. If your feet are different sizes, buy based on the larger one. Talk to an expert. Shoe salesmen and personal trainers can study your stride (步伐) and the shape of your feet. 74 75 Many trainers recommend switching footwear every three to five months, if possible, to maintain proper cushioning and support. One tip: if you have to tie your shoes very tightly to feel a good amount of support, they may be ready to go.
F. Replace worn shoes regularly. G. Usually they can recommend the best shoes to guard against injuries. |
