You\u2019d think it would be easy to know when a pair of shoes fits perfectly, but it\u2019s not always so straightforward. Sizing\u00a0 is important for all types of footwear. However, it\u2019s particularly crucial for all<\/span> types of sneakers<\/span><\/a><\/span>, as they\u2019re made for continuous movement.<\/span><\/p>\n So, <\/span>how should <\/span>sneakers fit<\/span>?<\/span> The footwear pros at Vionic are here to answer this sneaker industry question and provide helpful guidance on determining the proper fit for different types of trainers and<\/span> walking shoes for women<\/span><\/a><\/span> and men.<\/span><\/p>\n Ill-fitting shoes can cause a broad range of <\/span>foot problems<\/span><\/a><\/span> beyond just blisters, bunions, ingrown toenails, and general <\/span>foot pain<\/span><\/a><\/span> and discomfort. The wrong size can result in shin splints, alignment issues, and overpronation, which often leads to severe heel pain in the form of plantar fasciitis or Achilles tendonitis.<\/span><\/p>\n These foot conditions can be severely debilitating, sometimes preventing people from putting any weight on their feet. Needless to say, selecting shoes that are too long, wide, or narrow can result in serious foot woes.\u00b9 <\/span>Finding the perfect fit for tennis shoes<\/span><\/a><\/span> isn\u2019t rocket science, but there are a few things to keep in mind <\/span>when choosing the <\/span>right shoe size.<\/span><\/p>\n Properly fitting sneakers will:<\/strong><\/p>\n Most sneakers are intended to be worn with socks, especially active styles like the running sneaker. For this reason, make sure you always try on trainers while wearing socks. The same goes for <\/span>casual sneakers for women<\/span><\/a><\/span> and <\/span>casual sneakers for men<\/span><\/a><\/span>, unless they\u2019re meant to be worn barefoot. Also, keep in mind that not all socks are created equal. If you plan to wear a pair with thick athletic socks, try them on with dress, sheer, or otherwise thin socks won\u2019t cut it.<\/span><\/p>\n Additionally, if you wear <\/span>orthotic insoles<\/span><\/a><\/span> with your sneakers, be sure to put them in before trying them on. Inserts can be placed over the footbeds or in place of the existing insoles.<\/span><\/p>\n You slip into a pair of athletic shoes, and they feel good on your feet\u2014not too loose, not too tight.\u00b2 But how do you know if they’re the right fit? The finger test can help<\/span> find the<\/span> right size<\/span>.<\/span><\/p>\n While wearing the shoes, place one finger between your heel and the heel counter (back of the<\/span> running sneaker<\/span>). Ideally, it will slide in easily but feel relatively snug. If you can\u2019t get your index finger in or have to force it, the sneakers are probably too small. If you can effortlessly fit two or three fingers behind your heel, they\u2019re too large. This test will help you know how much room you should have in your shoe<\/a><\/span> for the best fit.<\/span><\/p>\n Running is one of the purest and most popular forms of exercise. Apart from getting the right gear, it doesn’t cost any money. And, weather permitting, you can do it anywhere, anytime.<\/p>\n Having said that, every runner needs not only proper footwear but also properly fitting footwear. How are running shoes supposed to fit? Following the <\/span>sneaker <\/span>fit <\/span>guidelines, we outlined above is a great place to start, but we\u2019ve got a few more pointers for determining the right size, regardless of whether you have flat feet, wide feet, or something in between.<\/span><\/p>\n When it comes to running shoes, wiggle room is of the essence. When you hit the trails or pound the pavement, your toes endure substantial impact with every stride.\u00b3 Without any space to move, they can’t effectively absorb this impact. This can wreak havoc on your feet, ankles, calves, and hips.<\/p>\n As we mentioned, most shoes should be between 0.5 to 0.65 inches longer than your feet, but runners may want to err more toward 0.65 inches of additional space. The finger test can tell you whether you have enough wiggle room. If you can’t fit your index finger behind your heel, the running sneakers are definitely too tight.<\/p>\n Another trick for knowing whether sneakers fit properly is to press your thumb down on the front of the shoe, right at the tip of your longest toe. When standing or crouching, there should be between 0.35 and 0.5 inches of space between your longest toe and the front of the<\/span> athletic <\/span>shoe <\/span>(or about the width of your thumb).<\/span><\/p>\n This is where the idea of wiggle room comes in. The toe boxes should provide you with plenty of room to move your toes while standing up in running shoes.<\/p>\n Running shoes that are too large can cause foot problems, but tight-fitting sneakers are a common mistake. To avoid the issue, many runners opt for a half-size larger than they normally wear.\u2074<\/p>\n This ensures there’s plenty of wiggle room for the toes, allowing your feet to properly absorb impact. And since the difference of one half-size is usually only between 0.13 to 0.25 inches, the risk of getting running shoes that are too large is low.<\/p>\n With that said, this really depends on the brand. If you’re browsing running shoes from a brand you’re familiar with, sizing up may be a good idea. On the other hand, if you’re considering shoes from a new company, you may want to try them on in a shoe store first. Otherwise, you can measure your feet carefully and compare your measurements against the brand’s size chart.<\/p>\n Foot shape<\/span> matters when determining how sneakers should fit. If you have <\/span>flat feet<\/span> or <\/span>wide feet<\/span>, finding the <\/span>right shoe size<\/span> can feel more challenging\u2014but it’s essential for preventing <\/span>foot problems<\/span> like <\/span>heel pain, blisters<\/span>, or <\/span>ingrown toenails.<\/span><\/p>\n For those with <\/span>flat feet<\/span>, look for walking or running shoes with built-in arch support and a firm midsole. A stability shoe can help correct overpronation and maintain proper alignment with every step. The right fit should feel snug in the heel without pinching the toe box, allowing space for your <\/span>longest toe<\/span> to move freely.<\/span><\/p>\n If you have <\/span>wide feet<\/span>, always prioritize width options. The <\/span>best shoes<\/span> will offer wide or extra-wide versions, giving your <\/span>foot <\/span>the space it needs without sacrificing the <\/span>perfect fit.<\/span> Shoes that are too narrow can compress your forefoot, causing long-term discomfort or <\/span>foot pain.<\/span> When trying on new sneakers, wear the <\/span>socks<\/span> you\u2019d use during <\/span>daily wear <\/span>or workouts\u2014and don\u2019t forget to test for <\/span>heel slippage<\/span> and<\/span> wiggle room.<\/span><\/p>\n Measuring your feet to determine shoe size<\/a><\/span> and the proper shoe fit is easy. We recommend checking both the length and width every couple of years or so, as your feet can expand throughout adulthood.<\/p>\n Follow these steps to measure your feet:<\/strong><\/p>\n Most people have one foot that’s ever so slightly longer than the other. You should choose your sneaker size based on your larger foot, as this will provide the most comfortable fit on both sides.<\/p>\n Are you ready to gear up for your next workout or slip into a pair of wear-anywhere shoes?
