These show little wear. "You need lightweight men's footwear that can perform and handle a rough day of training. Weighing a mere 26 ounces per pair, these ~Danner Men's 50130 Tachyon Tan Military Work Boots were engineered to be some of the lightest, most flexible work footwear ever made. As such, they're ideal for combat training and for daily use. Taking their typical Danner boots and completely overhauling them, Danner has removed the extra weight from these men's boots without neglecting comfort and performance. For superior weight savings, the ultra-light uppers are completely synthetic with the added benefit of an ultra-fast dry time. For optimal airflow and superior durability, these Tachyon boots have an open-cell polyurethane footbeds. Light and shock-absorbing, polyurethane provides maximum protection from impact. The open-cell structure of these tan boots enables air to travel, creating cooler interiors to help you feel comfortable throughout the day. Providing additional shock-absorption, the EVA midsoles are soft, light, and flexible. EVA is a durable plastic foam material that provides good cushioning and will absorb more force. Most uniform boots in this weight category have composite rubber outsoles, but this Tachyon footwear has true rubber outsoles for superior abrasion-resistance and traction. Featuring pentagonal lugs, these rubber outsoles will provide superior surface contact."
