This weighted technology was originally developed by taking traditional sandbag weight training principles and incorporating them into a shoe that’s healthy and safe for the wearer. For years, ankle weights have been worn by athletes to encourage good muscle and bone development while also increasing exercise intensity and improving speeds of weight loss. A popular method of fitness training in the military, the weights load the body and result in accelerated weight loss and enhanced fitness levels.

However, training with heavy and uneven sandbags or running with ankle weights can result in injury and put extra pressure on joints that have to deal with both the load and the uneven distribution of weight. Unlike training with ankle weights, Airun have been designed and developed by a leading Sports Science Professional to challenge the body without compromising the integrity of the joints. Since the weights are fixed, secure and bio-mechanically engineered to work with your centre of gravity, they incur minimal stress to the joints.



The weighted insoles will help you increase the exercise value of normal activities by 3 times. For example, when worn during power walking, you can expect to burn approximately 300 calories with every 30 minutes you do.

The weighted insoles of Airun load the body and encourage the heart rate to increase. When your heart rate increases during exercise, you are working out aerobically.

Along with improving your cardiovascular health, this method of exercise is most effective in combating excess fat reserves because it burns carbohydrates quickly, which if left unattended to, will turn in to the fatty deposits that will prove hard to shift later.

Airun Plus are supplied with two weighted insoles so you can increase the intensity of your workout when you are ready and decrease it when you need to.

The lightweight insole:

The lightweight (red) insole alone weighs approximately 106grams. Added to the trainer, the combined weight is approximately 454grams. The light weight insole has been designed for walking, running, vigorous exercise or when first starting out. This weight is designed to ease you in to loading the body and should be used before progressing on to the heavy weight.

The heavy weight insole:

The heavy weight (brown) insole weighs approximately 588grams. Added to the trainer, the combined weight is approximately 938grams. The heavy weight is designed to offer a progression in exercise intensity from the light weight insole. Using the brown insole delivers an increased calorie burn and increases the results of strength and toning to the lower body
