My Nike ones didn't last long, but I work out at the gym (including running on a treadmill), and my Underarmor ones have lasted me over a year...so as with everything Underarmor, I highly recommend. If this continues, I would suggest investing in Hiking Boots. I bought a pair (for hiking mostly) from Bass pro shops on sale for $40. They are pretty ugly, but they are SO good for walking in general not only hikes!
