I bought these after and extensive session in the Betws-y-coed store where I tried everything on. Having had them on for about 2 hours my feet still felt comfortable. The next day I tackled Snowdon (went for something easy to break them in). After 6 hours of easy walking they were solid and light. My feet had no signs of blistering and the boots felt like robust slippers. A week later I decided to challenge myself and the boots. Tryfan in the wet!! The Vibram soles stuck to the rocks like glue, I felt safe and secure on the exposed scrambles. Having waterproofed them after the previous weeks session up Snowdon I was keen to see how long they would keep me dry. After tackling Tryfan I was soaked but my feet still dry. Continuing through the Glyders to Devils Kitchen they continued to grip, support and fit comfortably. Then as the heavens really opened up I slogged it down though the cascading water at Devils kitchen.
At the end of this adventure, I was soaked, my feet were very dry, warm and comfortable The Gore-tex lining helping to keep the feet vented and dry. These are the boots I enjoy wearing so much that I plan to be in the hills every week. North Face are the brand you can trust when you are on the side of a mountain in all weather.
