After I purchased these I started to get skeptical, after reading reviews about yun express (all bad, say it’s a scam, etc.) so I thought I got burnt. I ordered on April 24, and received them on May 14. They were exactly as advertised, extremely lightweight, and comfortable. Let’s see how long they last! (Even if they don’t last long I’ll still buy another pair because they are the most comfy safety shoes I’ve ever had)
