Poorest pair of Hi-Tec boots I've owned out of four sets. The former three were Altitude IV's. Lace eye hooks (2) fell out within a week and laces on both shoes broke the next. Now I'm down to replacing the laces and attaching the eye hooks with pop-rivets to the shoe. Good thing I didn't take them on an extended hike or I'd be walking out barefoot.<br /><br />Today I ordered another pair of the earlier Hi-Tec Altitude IV boots which have proven to be better quality.
