Tips for Shock Doctor Groinguards

The Shock Doctor G5 is specially designed for women and protects the groin and lower abdomen. Available in multiple sizes, refer to the size chart on the product page for the right recommendation.

Wipe the groinguard after every training session with a damp cloth and let it air out. Never store it damp in a closed bag.

Frequently Asked Questions — Compression trousers groinguard Shock Doctor Core Bioflex

Why are groinguards in boxing so different from regular cups?

A "regular" cup only protects the groin. A no-foul protector in boxing protects the kidneys, liver, and groin.

In boxing, the chance of taking punches to the liver or kidneys is much greater than in kickboxing. Extra protection is therefore needed to minimize the risk of injuries and damage.

Is a groinguard mandatory?

Yes, usually.

A groinguard is often mandatory or recommended. For boxing, kickboxing, and karate training, for example, it is recommended. In krav maga and self-defense systems, it is mandatory. The area protected by the groinguard is, of course, highly vulnerable to injury.

During exams and competitions, a groinguard is always mandatory for both men and women.

Can you wash groinguards and cups?

Yes and no.

This depends on the brand and model. You can almost never wash the cup (the hard part), nor do you need to. Most regular groinguards are built into a kind of sports brief (jockstrap). You can remove the cup and wash the brief.

The larger kidney and groinguards (No-Foul) designed for boxing obviously cannot be washed in a washing machine either. This really shouldn’t be necessary. You can simply wipe them down and dry them to keep them fresh. 

Naturally, you can’t wash the steel groinguards either. The metal is not designed to withstand this.

What size groinguard should I get?

When choosing the size of groinguards, the main consideration is waist circumference rather than the cup size itself. For each groinguard, we have included a unique size chart (in the size selector and below in the product information) for that specific brand and model.

What is the background of the Shock Doctor brand?

Shock Doctor has grown from the undisputed leader in mouthguard technology into the world's leading innovator in sports protection. Our belief in combining design and technology to achieve better protection and performance is now trusted by fearless athletes across a growing range of products and sports, from youth to amateur to professional.

In addition to mouthguards, Shock Doctor is also at the forefront of protecting crucial and vital areas of the body. They make the best athletic cups and groinguards for men and women. These are used in intense combat sports, such as boxing and kickboxing, as well as in other contact sports, such as ice hockey, field hockey, and rugby!
