I find Glads very slippery on flagstones, but maybe they're all like that. They are very comfortable, but I find them a bit long to get a size that's wide enough for me.
Bought a pair of Walsh Ultras at the Tigger as I'd inadvertently brought along an old pair of shoes. The Ultras were good on Mickleden - rubbed slightly on big toe towards the end, but no blisters.
