How should shoes fit? The complete guide

Remember those times you'd run into the shoe store as a kid, excited to try on all the shiny, cool shoes on the shelves? You'd open three or four boxes and try them all on, desperately trying to convince your parents to buy them for you.

Even if the shoes weren't a good fit, you didn’t want to worry about struggling with that whole process. You just wanted to walk out of the store with a super cool pair of new shoes to show off to your friends at school.

Whether or not this sounds familiar to you, the idea of trying on shoes and struggling to find the right size almost certainly is. Even though our foot sizes don’t change much as adults, there's still the struggle of finding the right fit.

Finding and buying the right shoes may feel like a losing battle at times, especially with different brand sizing, changing style trends, and uncomfortable fabrics. However, at Kizik, our experts are here to help! 

We've got experience in the world of footwear, and every one of our shoes is built to help you get the most comfortable, practical, long-lasting fit possible. In today's guide, we're going to break down what defines a perfect fit and how you can most easily find the one for you.

Let's jump right in!

The phases of fit

To really understand what makes a perfect fit, it's best to look at shoe fit in stages. From the moment you put on your shoe to two hours later, and even two years later, different aspects of your shoe will contribute to whether or not they fit well.

The trying-on phase

The very first phase where fit matters is the trying-on phase, when you first put on the shoe. 

Have you ever struggled so much to put on a shoe that you almost gave up on it, only to finally get it on and realize it's actually an excellent fit otherwise? This experience isn't uncommon, and it's typically due to poor design.

Regardless of how the rest of a shoe fits, it's essential that the opening is built properly so you can easily put your shoe on and take it off. 

If your foot hurts when putting on your shoes, it could be because the shoe's heel is too rigid and stiff, or it could be that the opening is too small for your foot. 

Forcing your foot into such shoes can hurt both your fingers and your heels, especially if your feet or hands are sensitive

Consider also whether you'll have to untie and retie your shoes to take them off or put them on. Just because there are shoelaces on your shoes doesn't mean they need to be used every single time you wear them.

At Kizik, our HandsFree Labs® technology solves all the problems of putting on and taking off shoes. Our patented technology provides an easy slip-on and slip-off experience that hugs your heel for lasting comfort and that stays on your foot. Plus, there’s no need for daily shoe-tying.

A pair of Kiziks might just change your life, especially if you have kids.

General wear

The phase most of us think about when it comes to the fit of shoes is the general wear phase. This is the nitty gritty, everyday grind that your shoes go through.

Unfortunately, it's not easy to tell exactly how a shoe will feel during this time when you’re trying them on. Sometimes you won't notice that your shoe is too tight around the toes, too narrow near the bridge, or too loose at the heel, at least not until a few thousand steps of wear later.

One of the specific ways that shoes might not fit well during the general wear phase is if there is not enough space around your toes. Do your toes push up against the end of your shoe a lot? This could be a problem both for your foot comfort and for the lifetime of your shoes. 

Without plenty of toe room, your shoes will go through extra wear and tear in a shorter period of time. With poor fit, there’s also the potential for holes along the seams of certain shoes, especially low-quality ones.

In fact, extra pressure on any part of your foot can wear out your shoes more quickly and cause discomfort over time. This can be compounded the longer you wear your shoes each day and the more active you are in them. 

Active lifestyle wear

If you're living an active lifestyle, the perfect fit is even more critical. Perhaps your day takes you from the gym to a long commute to work, where you'll do a few thousand steps within an hour. After work, more commuting, errands, social events, chores at home, or time to relax outdoors can spell even more stress on your feet.

If your shoes don't fit, an already challenging day like this is almost guaranteed to be miserable and exhausting. Few things can ruin your mood faster than foot pain and other discomforts like back pain that tend to follow it.

On the other hand, super comfortable shoes can give you one less thing to worry about and even be a bright spot in an otherwise tough, busy schedule. With our Rabbit Foam™ outsoles, your feet will be ridiculously comfortable all day long, so you don’t have to worry about sore feet ruining your day.


It's essential to keep long-term factors in mind when shopping for footwear unless you plan on overhauling your shoe closet every season. 

Thankfully, we don't have to worry about our shoe size changing much as adults, at least compared to the change every few months or even weeks that we experienced as growing kids. This may be a welcome grace to our budgets, but it's not the only factor that could affect shoe fit over the long term.

Durability is also a vital part of finding the right fit.

For example, while a shoe may fit well at first, if the material and build aren’t durable, the shoe could lose its shape and become too loose to be comfortable. Alternatively, a snug fit with padding might be comfortable for a time, but if and when the padding wears out, the shoe could feel more like a pokey straight jacket.

It's impossible to promise a certain lifespan for any shoe, due to the vast range of factors involved. However, ensuring you choose only high-quality materials and buy thoughtfully designed shoes that are built to last is essential. Cheap materials are a sure sign that shoes won't last.

Intended uses can influence fit

The intended use of the shoe is important when it comes to fit and durability as well. Just because a pair of dress shoes fits well enough for the office doesn't mean they’re going to feel comfortable on a long commute or walk in the park. This may seem obvious, but the more you wear shoes outside of their intended use cases, the more they wear down and lose their perfect fit.

Thankfully, athleisure shoes like our styles here at Kizik are designed to be super versatile. They're perfect for commutes, light workouts, errands, walks in the park, nights on the town, days in the office, and even wearing around the house.
