Typically this measurement only considers length and not width. Sizing does vary slightly per manufacturer because each vendor uses their own set of lasts when creating the shoes, so these shoe size comparison charts are only estimates.
Shoe Size Selection Tips
- Always try to find online reviews of the pair you want to buy, from real people who have actually purchased the product. Best places to look for real reviews are amazon.com and YouTube.
- Measure your feet in the evening hours because feet expand throughout the day.
- If you're buying shoes for a first time walker, then be sure to purchase a pair with flexible soles and a small amount of extra growing space. When shoes are too big, blisters are likely to form while a tight fitting shoe will chafe your little one's feet and cause redness.
- If you're buying shoes for your child, take into account that footwear for children usually lasts for about four to five months. Therefore, create a household budget that includes enough funds to pay for several pairs of shoes.
- To find the most comfortable footwear for you, consider buying shoes for both the width and the length of your feet. Some people need to purchase shoes that are narrow because they are never comfortable on wide one, or the opposite. You may even need to buy shoes that are especially slim or extra wide.
- If you start with a known fact, there is a better chance of heading in the right direction.
- Remember that laced shoes give a little more leeway than slip-on shows. Some adjustments can be made by the thickness of the socks you wear. Those not wearing socks, are probably buying sandals, which do not always fit perfectly.Furthermore, keep in mind the shoes that are slightly large can be adjusted through the thickness of the socks, or for ladies wearing flats or pumps, there is a liner that can be purchased to help the shoe fit better.
- If a lot of walking is going to be involved, go beyond the size that is a little greater. Your foot is going to swell during the day, and the larger shoe will be more comfortable. You do not want it too large. The constant rubbing will cause blisters. Also, the shoes cannot be too large, because they would be very loose in the morning hours.
- When buying footwear online, take into consideration the type of activities you'll be performing in the shoes. Hiking shoes should be durable and waterproof. They should also cover your ankles to provide protection from snake and bug bites as well as rocks and plants. If you are buying regular workout shoes, then make sure that they come with a cushioning insert to protect your feet and legs from the activity. Dress shoes should feature a thick sole and quality construction.
Shopping Online And The Risks Involved When Choosing The Size
Shopping from a catalog or an online store has always carried a minor concern of uncertainty, which can offset by the increased selection and usually lower price.
Therefore, if buying online is the way you want to go, let us be the first and possibly last stop. With all the charts from all the countries and manufacturers making the shoes at your disposal, your task becomes easier. You need a starting point, like men's loafers size 9, or women's heels, size 5, double A.
Then you find the pair you want to buy. With your size information in your hand and the wealth of information from this site, and with a little luck, you should be able to find some way to make the comparison between what is being sold and what you need. This will ultimately allow you to make the right choice.
Finally, many people, of both sexes, like to exaggerate about the size shoes they wear. Large men will wear big shoes. Allegedly, women will often claim to wear a shoe smaller than their shoe size, or that is what Hollywood would have us believe. The key is to be truthful.
In the movie 'Steel Magnolias', Dolly Parton runs a beauty shop and the subject of shoes came up. She says something to the effect that she wears a size six, but because a size seven are so comfortable, she buys a size eight. The numbers may be off, but as we all know, show sizes can vary, and we do not know where the shoes she allegedly purchased were from a country where a size 6 may equal a size 8. Do your homework ahead of time.
Be honest with yourself and always remember, shoes, which are a little loose are usually more comfortable than those that feel a little tight. So when picking a size from among the charts study the variances among the countries and the shoe manufacturers and make your best choice.

Finding the Perfect Fit
In order to find the perfect fit for your shoe size, make sure you measure both feet. Some people have one foot slightly larger than the other. Make sure you choose the size that fits the larger foot.
Also make sure you consider the socks or tights you will wear most often with your shoes. The size of your foot will increase with thicker socks or tights and therefore you may want to order shoes that are about a half size larger than you normally wear.
Another thing to consider is the time of day that you measure your feet. Try to do your feet measurements in the afternoon, when feet tend to be their largest.
If you require a wide width shoe and no wide width shoe sizes are available, try ordering a half size larger in the regular width to compensate for the width of your foot.
Sizing Discrepancies
Please note that it is never a good idea to buy shoes based solely on the conversions shown in the table above.
Before buying shoes online, please check the sellers return policy, to make sure you are coverered in the off chance that you end up with a size that does not fit perfectly.
Deriving the Shoe Size
The length of a foot is commonly defined as the distance between two parallel lines that are perpendicular to the foot and in contact with the most prominent toe and the most prominent part of the heel. Foot length is measured with the subject standing barefoot and the weight of the body equally distributed on both feet.
The sizes of the left and right feet are often slightly different. In this case, both feet are measured, and purchasers of mass-produced shoes are advised to purchase a shoe size based upon the larger foot.
Each size of shoe is suitable for a small interval of foot lengths. The inner cavity of a shoe must typically be 15 - 20 mm longer than the foot, but this relation varies between different types of shoes.
