Mizuno will launch the "ALMIGHTY WU" series of work shoes for site workers on June 20th, designed to address challenges in wet and outdoor work environments by combining waterproofing and breathability.

*1 Certified under the JSAA's protective sneaker standard for general work (Type A).
For sites where workers are frequently exposed to water, such as sewage treatment, airports, and outdoor infrastructure, not only "water resistance" but also "breathability" and "comfort during long working hours" are crucial. However, existing waterproof boots and work shoes tend to be stuffy, leading to increased discomfort, especially on clear days or in high temperatures.
The "ALMIGHTY WU" series addresses the conflicting demands of waterproofing and breathability by adopting the highly waterproof and breathable film "HBR® Microporous" and redesigning the upper structure. This development ensures that site workers can feel comfortable while wearing the shoes.
The sales target for the "ALMIGHTY WU" series is 24,700 pairs (within the first year of launch).
