Sizing

Finding the right size without expert advice isn't easy. But our table will help you narrow down your choices.

Please note that the recommended foot length already includes ample toe room. Therefore, you do not need to add any extra space. We have deliberately designed this generous space because we unfortunately often find that shoes are bought too small and narrow.

Feet need at least a thumb's width, or about 1.5 cm, of space at the front of the shoe. Our shoes offer lasting, exceptional lateral support, but tend to shrink slightly over time. The foot, however, expands with movement and absolutely needs sufficient room for the rolling motion of the foot – so it's better to choose a size or two larger than too small. The supple upper material of our shoes is point-elastic and yields when needed. Where space isn't required and the foot doesn't touch the material, the upper shrinks slightly. After a break-in period, this creates a unique, individual fit.

Useful information

How do I measure correctly?

• Take a sheet of paper and a pen. Align the paper and your foot against a wall and mark the point where your foot meets the paper with the pen. Then measure the distance between the edge of the paper and the mark to determine your foot length.
• Make sure to measure straight. The measurement must be taken at a 90° angle to the stop edge or the wall.

Different manufacturers - different sizes

Shoe sizes are not standardized, so they vary depending on the manufacturer. This means that your usual shoe size may not be directly applicable to LUNGE shoes.

Shoes that are too small

Unfortunately, we frequently find that shoes are bought too small. If your toes are touching the front of the shoe, it's simply too small. You should have at least a thumb's width of space in the toe box, but feel a firm fit in the heel area.

If it doesn't fit right away

If your ordered shoes don't fit, an exchange or return is easily possible. There are no additional costs for you – returns and all other shipping methods are free of charge. Further information on returns and exchanges can be found here .

Size systems of the various manufacturers

Six different sizing systems are used for shoes and athletic shoes. And as if that weren't complicated enough, the conversions are done differently by each manufacturer. In practice, you can easily compare the English sizes of traditional shoe manufacturers, while the US sizes of athletic shoe manufacturers tend to be relatively similar. Even the conversion to European sizes varies considerably from manufacturer to manufacturer. Therefore, the European size – also called the French size – is often unusable according to the Parisian system due to this inaccurate translation. However, you can easily calculate it yourself using a simple formula: Your foot length in centimeters plus 1.5 cm for extra room in the shoe, multiplied by 1.5, gives you the European size. Since French sizes often differ by a quarter, a third, or half of the full size, you should always round up to find the correct size.

The width of LUNGE shoes

The width of the shoes should match the width of the foot. The circumference of the foot is measured at the ball of the foot, i.e., at its widest point. The medium width is H. Thanks to the exceptional elasticity of our vegan upper materials, our shoes can be used for foot widths of G, H, and J. Additionally, for those with particularly wide feet, we offer the Derby Walk and Derby Run models, which cover widths J, K, and L.

Special cases and on-site consultation

For unusual foot shapes or high demands, trained specialists should provide advice. During the consultation, trained specialists pay close attention to the foot. They can usually determine the size without measuring devices and also consider foot position and any deformities. In addition to instep height, they also pay attention to the width and depth of the feet. They focus on the voluminous foot, as feet cannot tolerate compromises. If the feet are significantly different in size, it may be necessary to purchase two pairs of shoes to ensure optimal fit for each foot.

In running specialty shops, an analysis of leg dynamics has become standard practice. This involves not only assessing barefoot movement in slow motion, but also, in the modern approach, examining the foot with shoes to determine its impact on the individual running style. A personal test run on a track makes the recommendations very easy for the runner to understand. Often, special insoles, custom-made insoles, or shoe modifications are recommended. The effort is worthwhile, as a personalized selection of well-fitted shoes enables pain-free movement and healthy foot loading – a value that cannot be overstated. This is a service that simply cannot be replicated through online retail.
