Tips for selecting the best shoe size
Other Customers & Websites
Find websites that have the shoes in stock and read reviews to see if other customers commented on whether they are loose or tight fitting for their size compared with other shoes they own. This can sometimes be an indicator as to if you should buy them on the larger size or smaller size you are used to as most people have a range of sizes within 1.5 they can fit into depending on brand, shoe style etc. Youtube is also a great place to search for the sneakers or shoes to see if you can find out more about how they fit.
Measure Your Feet
Measure your feet and write down the size, do this from end to end and also measure the width. You should do this in the evening when the feet have expanded but it also helps to take a recording in the morning also so you know how much variation there is. The best way to measure your feet is to trace them on a piece of A4 paper (provided your name isn't Shaq and then you might need A3) and then measure the length and width.
Foot Profile / Proportions
Consider the profile of your feet, some people have a more narrow foot and others have wider profile feet as a result you will find different trainer styles fit better for different people. Innersoles can be a good way to fill out space in cases where you feel you cannot fill out certain styles of shoe adequately. People even have different profiles based on their toe length & instep height which is the part from your toes sloping up to your ankle. Keep in mind shoe manufacturers cannot offer a variety of widths because it's not economically viable.
The arch height is the height of the grove between the ball of your feet at the front and your heel. Depending on the height of this concave area different shoes may fit differently. There are special inner soles that you can get from the chiropractor and elsewhere that can help to fill this. This can be a cause of back problems so it is something worth researching and visiting a chiropractor for a consultation.
Lace Ups Vs Slip Ons
Lace ups are more flexible and allow for more space than slip on shoes so it is better to get a slightly larger size than a size that is too tight and compensate with different sock thickness's. If you wish to wear them barefoot then you need to consider innersoles or going half a size to a whole size below your typical choice.
Looser fitting and more padded shoes are considerably more forgiving when used for long durations and doing lots of walking. Especially as your feet swell during the day under the pressure of... well, you!
When purchasing shoes online and considering the size try and look into the brand they are made by. If they are Adidas consider how this sneaker has fitted you in the past. If you have no previous knowledge then consult their official website. If in doubt you can always send them an email and ask them how their sizes fit or how a specific shoe design fits compared to others.
Sock Style Sneakers
Slip on sock like trainers such as the NMD City Sock by Adidas fits a little large if you plan to not wear socks, if you do wear socks then it still may be a little large. This kind of sneaker it is worth going half a size to a whole size down for a more snug and tactile fit.
What are you waiting for?
With all said you should now be better equipped than ever to go and buy those online sneakers you want without worrying that after all of the excitement waiting for the postman you won't be disappointed with the fit!
