A Brief Introduction To Crocs

Crocs Logo

Crocs (or Crocs Footwear) is an American footwear brand. Founded in 2002 by Lyndon “Duke” Hanson and George Boedecker Jr and has its headquarters in Broomfield, Colorado. The first Crocs were lightweight foam boating shoes and were first introduced in 2001 in Florida. Since then, there have been 300 million products sold worldwide.

Crocs are first known as foam shoes in bright colors, with a Swiss-cheese toe area and inspired by the Dutch clogs. These shoes have ports, or ventilation holes, to keep your feet dry and odor-free. Besides, the heel straps allow you to use the shoes as slip-on clogs or sandals.

Apart from its signature classic Crocs with over 20 colors, Crocs has developed new product lines, like Crocs sandals, boots, sneakers, and flip-flops. Crocs also distribute therapeutic footwear for recovery purposes, or for people whose jobs require all-day standing or walking. Besides footwear, Crocs also sells Jibbitz decorations, mainly for kids.

Why Crocs are so popular?

First, they are so comfortable, simple, lightweight, and easy to clean and wash. You can wear a pair of Crocs for many purposes, including going to work, shopping, playing, doing gardening/farm jobs, etc.

Second, they are also affordable and easy to find online or at any shoe store nearby.

And third, Crocs offer a heel of 1.6 inches, making you look taller, more confident, and more attentive based on height. There are two types of heels – platforms and slingbacks. You can pick a heel style based on your preferences.

Do Crocs Run Big Or Small?

Generally, Crocs are true to size with a loose fit to support your feet without applying pressure on them. The upper is gentle and the toe box is spacious with plenty of room for your toes. Plus, the heel straps provide adequate support while allowing you to switch between sandal mode and clog mode. These straps don’t cause blisters even at first wear.

However, there is no half-size option for Croc clogs, which is a con for many people. This isn’t a problem for Classic Lined Crocs or Baya Crocs, since these models are customized for a spacious fit. However, if you aim for other product lines of Crocs, like Crocs sandals or Crocs Crocband, you should be more careful while picking up your Crocs sizing.

How Should Crocs Fit You?

The exact sizing of a pair of Crocs depends on three main criteria – the type of Crocs, its purposes of use, and its type of fit.

Type of Crocs

Although Crocs are known for its loose-fit design, its sizing might differ depending on product lines. If you don’t have much time for sizing, you should choose Crocs Classics.

These clogs are designed with standard sizing and provide a comfortable fit for everyone. But this story isn’t true for other types of Crocs. For example, the Bistro Clog is a great choice for wide feet. Its toe box and upper are closed but are still more spacious than other Crocs.

On the contrary, Crocs Crocband will provide you with a snug fit, which is quite painful if you wear these shoes all day long.

Professional/Purpose of use

If you want footwear to walk shortly around the house or to clean your garden, Crocs flip-flops, Classic Crocs, or any Crocs will fit you.

But if your work requires hours of walking or standing, like a healthcare professional or a chef, you need to find ones that have a snug fit to secure your feet.

Types of fit

Crocs offer you three types of fits – roomy fit, relaxed fit, and standard fit.

  • Roomy fit

Roomy fit is the most popular fit type for Crocs. This fit type allows generous space for your feet, from width to length. And there is no worry about slippery since the straps at the bottom will secure your feet with the shoes. Also, there is plenty of room on the top for air ventilation.

  • Relaxed fit

Unlike the roomy fit, the relaxed fit provides less room for your feet. The sides of your feet reach the shoes’ walls, but your toes can’t reach the shoes’ front. There are also heel straps or laces to secure your feet while lessening cramps and rubbing on your skin.

  • Standard fit

Standard fit gives you a snug yet comfortable fit among the three fit types. With the standard fit, your feet are kept securely with little to no slipping as you move. The shoes’ side, arch area, and upper should hug your feet comfortably.

Roomy fit vs Relaxed fit vs Standard fit – Which fit is for you?

If you have wide feet, you should choose the roomy fit to get the most space for your feet. If you have regular feet but want a loose-fit feeling to walk around the house, you should choose the relaxed fit. And finally, if you prefer a snug fit, the standard fit should be the one you choose.

Sizing modifications

All shoes stretch out slightly at first wear. But do Crocs stretch like other shoes, and if yes, how much will they stretch?

Crocs also loosen in the first several usages. However, they won’t stretch too much after that, unless you expose them to the sun for hours.

Once again, since Crocs only come in whole sizes, you will have to resize your shoes to get them perfectly fit you.

In most cases, you should choose a half size up when wearing Crocs. If the shoes are oversized, you can wear socks with your Crocs to make the shoes better fit your feet.

If the shoes are too tight, you can stretch them out by putting them in the freezer overnight. You can also warm your Crocs with some towels in the dryer in ‘extra dry’ mode. When the Crocs are warm, wear three pairs of socks on your feet and wear the shoes immediately to stretch them out.
