At first I thought these were the greatest boots ever. They're light and comfortable. I ignored my friends advise not to buy them. She said her upper boot pulled away from the lower rubber tread after 4 months. I was singing their praises and then 3 months and 2 rainstorms later mine were falling apart. The fabric of the boot is also wearing thin. This is a terrible product and under armor should be ashamed to put their name on it.
