This winter I’ve finally got round to trying out slip-on snow grips for my shoes, and these work a wonder.
They are rather fiddly to put on (and I would certainly recommend erring on the order of buying a larger rather than smaller size), but once on my trainers they turned slipping and sliding into easy walking.
Given the very impressive amounts of grip added by these I highly recommend them if you are wearing shoes or trainers. If you are wearing boots, however, I suspect even the largest size would struggle to fit properly over the toes.
You can buy the Sticky Feet slip-on grips for ice and snow here.
