1. Introduction to shoe and sandal sizes
Choosing shoes not only affects appearance but also directly affects the health of the feet. In particular, choosing the right shoe and sandal size helps the feet feel comfortable, minimizing problems with foot pain, calluses and long-term bone and joint problems. However, many people often do not pay attention to the difference between shoe size and sandal size, leading to uncomfortable wearing of sandals, especially when choosing the wrong size.
Shoe and sandal sizes are often divided according to different systems depending on the region, such as US, UK, EU. Choosing the right shoe size is essential, but choosing the right sandal size is equally important. Since sandals often do not have as many details to hold the foot as shoes, choosing sandals that are too loose or too tight can lead to inconvenience when moving.

2. The difference between shoe size and sandal size
Although shoes and sandals both serve to protect and support the feet, their sizes are significantly different. This comes from the design and purpose of each product. Shoes usually have a back strap or an entire structure that surrounds the foot, helping to keep the foot in place while moving. Meanwhile, sandals have an open design, do not cover the entire foot, and do not have a back strap (except for some sandals with a back strap).
Due to the open design, sandals are often loose if the wrong size is chosen, especially when the sandals are too big for the feet. Conversely, if the sandals are too small, the feet will stick out of the sole of the sandal, causing discomfort when moving.
Also, each shoe brand may have a different size conversion chart, so choosing the right shoe size does not mean that the sandal size will be the same. Your foot size may fit into one shoe size, but when switching to sandals, especially sandals with different designs such as flip-flops and slides.

3. If I wear size 42 shoes, what size sandals should I wear?
So if you wear size 42 shoes, what size sandals should you wear ? The answer depends on a number of factors such as the design, material and style of sandals you choose.
- How to convert shoe size to sandal size : Normally, if you wear size 42 shoes, you should choose sandals of the same size or increase by 0.5 to 1 size depending on the design of the sandals. For loose and airy sandals such as flip-flops or slides, increasing by half a size will bring a more comfortable feeling. However, if you choose sandals with a back strap or a foot-hugging design, it is more reasonable to keep size 42.
- The material and design of the sandals affect the size selection : Sandals made from elastic materials such as rubber or soft leather can be suitable when you choose the right size. On the contrary, hard sandals such as plastic or PU will need a larger size to avoid causing foot pain. Especially for sandals with horizontal or back straps , you need to try carefully before buying to avoid the case of the sandal straps being too tight or loose.

4. Notes when choosing sandal size from shoe size
To ensure you choose a pair of shoes that fit and are comfortable, here are a few things to keep in mind:
- How to test and check the fit when buying sandals : Make sure that your toes and heels do not stick out of the sole of the sandal. When trying on sandals, stand up and take a few steps to check the stability of the sandal. For sandals with straps, you need to check that the straps hug the sandal properly and do not cause discomfort when moving.
- Tips for choosing comfortable slippers : If you often buy slippers online, measure the length and width of your feet at the end of the day when your feet tend to expand the most. This will help you choose the most accurate size. In addition, carefully refer to the size chart of each brand and do not hesitate to contact the supplier for detailed information if necessary.
