I've worn these a few times and there's some dirt, but the soles aren't worn down and they're still perfectly wearable! The ML610 from NEW BALANCE. The Decon model, featuring new outdoor colors, has arrived for the "610T" training shoe, which was introduced in 2011 for entry-level users. Molded rubber on the upper and easy-to-remove drawcords have been adopted to make it more suitable for outdoor scenes. With original features such as the ABZORB sole, which has comfortable cushioning, this pair is perfect not only for trail running, but also for walking and outdoor activities. Thank you for looking.
