They saved me from being stuck at the bottom of a hill. I'd already suffered a pretty bad hill, to the point it took me 20 mins to negotiate. No matter how much I tried, pulling off in 1st 2nd 3rd it was a nightmare.
The socks made a huge difference. Hitting the hill with confidence and not the slightest slip. Vans, BMW's, Merc's and even 4x4's were having big problems. I just drove on by.
