Since the foot is in a different position when you wear heels, you might need to size up a half size or so to give the foot enough room to lay comfortably inside the shoe. Look out for telltale signs of an overly tight shoe like bulging at the toes or uncomfortable pressure around the back of the heel.
You want your heel to move as little as possible when you walk. Across the width of your foot, you can allow a little extra room here. Round the ball of your foot you want to feel secure, but not squished. Make sure there's a bit of space for your toes and that you don't feel too much pressure around your footbone.
A half-size represents a 1/8” difference. It may not seem significant but is enough to distinguish between comfort and discomfort. Because there is no standardisation for shoe sizing, a half size difference will also depend on the brand of shoe. With some makes, a half size will be more significant than others.
When your foot bends to take a step in a new shoe, your heels should slip slightly. 1/8” movement is normal but can feel like much more. Loose slipping in the heels will not cause blisters when broken in gradually, but wearing shoes that are too small and tight will cause friction and then blister.
If your feet are comfortably pushed into the front of your pumps, you shouldn't have more than 1 cm between your shoes and your skin. If your heels are popping out of the back, they are too long for you.
There is approximately a 1/6" difference between each half-size (e.g., between 9 and 9.5, between a 9.5 and a 10, and so on) For every half size up, the width (across the ball) will increase by 1/8"
Properly fitting shoes stay in place as you move, but if the shoes are too big, you will almost certainly have painful blisters by the end of the day. Other painful effects of wearing shoes that are too big include: Corns and calluses: caused by excessive pressure on the toes.
Shoes that are on the tighter side are likely to rub, and since this friction can cause blisters, it's best to have a bit of wiggle room. The ball of your foot should fit comfortably in the widest part of the shoe, and at the heel make sure that you have some room for slight heel slippage.
Shoes will typically stretch all on their own as you wear them. Leather shoes, whether it be men's dress shoes or women's heels, will fit over time. But if they are too tight and uncomfortable to wear in, try some of these easy hacks to stretch your shoes up to half a size or so to accommodate your feet.
Corns and calluses are foot deformities that are often caused when you wear shoes that are too tight, through friction from your toes constantly rubbing in a pair of shoes with reduced toe box volume. Aside from the pain and aching, the cramped atmosphere can form painful and unsightly corns and bunions.
Interestingly enough, a study by the University of Utah found that, “the heel-down posture increases the economy of walking but not the economy of running… You consume more energy when you walk on the balls of your feet or your toes than when you walk heels first.” So: Run on your toes, walk on your heels!
Check the space at the end of the shoe.
Stand up and make sure there is 3/8" or 1/2" (about the width of your finger) between your longest toe (usually the second toe) and the end of the shoe.
If there's a difference in size between your feet, take extra care when choosing shoes. If one foot is 1½ sizes bigger than the other (or more), it's best to buy shoes in non-matching sizes. Some retailers have 'split-size' policies: you could buy one shoe in size 8 and another in size 9 ½, say.
It is a commonly known fact that high heels are bad for you, with prolonged wearing leading to both a multitude of short-term problems such as corns and long-term problems such as bunions and back pain.
If you're trying on a shoe you plan to wear all day long, judge the fit at the end of the day when your feet are fully expanded. A half size in shoes is only 1/8 of an inch in added length. Shoes size can vary for many reasons, from sports injuries to weight gain and age.
There should be about half an inch between the end of your longest toe and the front of the shoe. If you have small hands, this is about the size of the tip of your index finger. If you have large hands, it's about the size of the tip of your pinky finger.
If you're between sizes, we recommend going up. As you can see, the difference of one whole size is only about a half-inch (less than 1 centimeter). The difference of a half size is—at most—a quarter of an inch. Opting for a larger shoe won't make a huge difference in fit, but it will be more comfortable overall.
There is a difference of 1/3 of an inch between a 9.5 and 10 shoe size. This may not seem like much, but it can make a big difference in the fit and comfort of a shoe. A 9.5 may be too tight, while a 10 may be too loose. It is always best to try on both sizes to see which one fits better.
That's the FIT difference! Our shoes come in 19 sizes: From 4 to 11 in whole & half sizes, plus whole sizes 12 to 14. There is approximately 1/6” between size increments, so a size 9 is 1/6” longer than an 8.5 and 1/3” longer than a size 8.
If you are looking for a comfortable, supportive shoe, then you should opt for the larger size. I wear a size 10.5 and can often wear a 10 or 11 without problem. I'd imagine you can wear a 9.5 or 10.5 without an issue. There shouldn't be a big difference.
Heels should fit securely in the back of your foot without slipping off or rubbing uncomfortably. The heel should be snug, but not too tight. You should be able to wiggle your toes and feel some room in the toe box. It's important that the heel fits well, as an ill-fitting heel can cause discomfort and even injuries.
Painful Heel Conditions Caused by Excess Weight
Plantar fasciitis is a major cause of heel pain nationwide, and being overweight can exacerbate the problem. The added pressure of extra pounds can cause flat feet, placing extra strain on the plantar fascia and making walking or standing extremely painful.
"A thicker heel will give you better balance and may help relieve some pressure by distributing the weight on your foot more evenly, says Morin.
