Both performed great and each lasted 3-4 years of use (and abuse). I ordered another pair of Spenco and they were comfortable. We were constantly walking over super uneven and pointy lava rocks and I didn?t feel a thing! I guess this was so each book had a minimal content to maximize the cost for us to read their story. These are very flattering. Beautiful shoes, but they run almost a whole size too large. It worked great and was easy to install. Technical details- don?t get clever with the sizing. These were too long and too baggy. Then guess what.
