I purchased these boots two or three months before hiking the West Coast Trail in British Colombia. I hiked at least 30 miles in them (with and without pack) before embarking on my trip and had no issues with blisters or fit. I've bought other Salewa shoes before so I had high hopes for these boots.

Unfortunately, they didn't meet my expectations. As the terrain became more difficult (cambered sand, deep mud, tricky climbs) my feet became more blistered. By the end I had blisters on blisters (balls of both feet, most toes) and was doing minor surgery on my feet at night and spending a lot of time taping up in the morning. I got blisters through moleskin. I wore the same socks I've always worn with my hiking shoes (Wrightsocks).

That said, the Gore-Tex held up wonderfully, they are very lightweight, and I can imagine boots which would give significantly worse blisters in the same wet and unsteady conditions. The soles were nice and grippy in super wet and muddy conditions and I never slipped.
