Why Are Your Boots Too Big?
There are a few reasons your boots could be too big. It might have been an impulse buy, where you sacrificed size for style. Maybe it was an online purchase and you can’t return them.
It might not be a new pair of boots. Your old faithfuls, which are your “go to” boots, might have stretched with wear. It could even be the time of year. Feet that have swollen during the hot summer months can be smaller when the weather is cold. If you have lost weight, this can also affect your foot size, strangely enough!
No matter what the reason is, boots that are too big are just not comfortable. Your heels could be slipping and causing blisters, and you might feel your feet are lost inside the boots.
So, other than throwing them in the trash or donating to charity — what is the solution?
Wearing Insoles to Make Boots Smaller
One of the easiest ways to make boots smaller so they fit our feet well is to wear insoles. They sit in the base of your boots and push your feet upward. This will fill in the gaps created by your loose footwear, making them snug again.
There are many different brands and sizes of insoles, let’s find out what to look for in an insole.
Choosing Insoles for Boots That Are Too Big
Check out the shape of the soles of your boots before choosing an insole. You want some that are going to fit well and not exacerbate the problem by moving around. Some will be sized to fit your boots, while others can be trimmed to fit.
You also need to make sure that the insole fits your foot. You can do this by standing on the insole on the floor. It should encompass your foot from heel to toe and also feel comfortable.
If you wear your boots for work, or are on your feet a lot, you want an insole that will last. There are cheap insoles out there, but the chances are they won’t be durable.
The whole point of insoles for boots which are too large is to make them fit. Consider the thickness of the insoles and the amount of padding they offer. If your boots are only a fraction too big you don’t need a pair that are too thick.
Need to fill half a size or more? Choose a thicker insole.
The added advantage of padded insoles is that they absorb the impact placed on your feet when you walk. This can help relieve stress on not just your feet but your ankles, knees, and back, as well.
Adding an extra layer into your boots could make your feet sweat more, however. Insoles with antimicrobial properties can help prevent the growth of bacteria which make feet and boots smell.
Generally, it’s recommended that you remove existing insoles when placing new ones in. However, the object of the exercise here is to decrease size, so leaving your original insoles in your boots might help.
This video can help guide you in fitting your insoles.
Frequently Asked Questions
How Do I Know Which Insoles Are Best for My Big Boots?
We have highlighted some of the features to look for in an insole. One of the main ones to take into account when your feet are floating around in your boots is their thickness.
If you just need a small adjustment then thin ones will be fine. If your feet are walking out of your boots, look for thicker insoles.
Will Thick Socks Help My Boots Fit Better?
Wearing thicker socks may help in some cases. However, they can also make your feet sweat more and you feet are still likely to move in the boot. This might result in blisters on your feet. Insoles are a more suitable option.
How Can I Tell If My Boots Are Too Big?
There are a few ways to check if your boots are too big.
Tie up the laces, and if the shoelace panels overlap, then they are too wide. If your feet are slipping and sliding in your boots when you walk, they are too big.
Finally, if you press the top of your boot in front of your big toe when standing, and it meets the sole, then yes, it’s too big.
Which Insoles Are Best for Loose Boots?
The choice of insoles when your boots are too big will depend on the amount of space in the boots. If it’s just a little, then a thinner insole like the Samurai will suit. If you have a lot of space to fill, a thicker option, like the Timberland would be better.
Both of these products provide additional support and cushioning for your feet. The ultimate choice is yours.
