MUSCLE TRAINER AB-3300 Color: TRICO Size: 24.5cm These are training shoes, 1.4kg per shoe. They show signs of use, but are still in usable condition. Please understand that these are used items before purchasing. Muscle Trainer, training shoes, were developed with the desire to "have people exercise in their daily lives" for those who "don't have time to exercise, or can't stick with it." Since its release in 1999, it has been used by many people for walking and training, including adventurer Yuichiro Miura. Muscle Trainer Walking is a light-load training shoe, approximately 1.4 kg per shoe, that allows you to exercise efficiently during your commute or work. The moderate load encourages aerobic exercise in a short amount of time, efficiently burns fat, and strengthens the core. By adopting a weight balance sole containing iron particles, patented in 10 countries around the world, it achieves both an even balance distribution that does not hinder walking and flexibility. The upper is made of mesh material with excellent breathability and flexibility, and the sole has a round shape that is less likely to cause tripping and absorbs impact upon landing, allowing for comfortable walking. ◆ZR-0502
