In this past week, I've used these boots mostly going up & down a ladder. They're light compared to the pair I've designated as my digging boots, but are sturdy nonetheless for that type of work, though sturdy as they are, the flexibility in these boots is remarkable; it's like there isn't even a break-in period. So far, these boots have been exposed to mud, sewage water and typical construction material (sheet rock, calium silicate, etc.)Looking forward to further exposure of the elements this coming season.
