I had never seen these before until out shopping in the middle of a bloody blizzard on Saturday! A lady came into a shop from the snow storm outside and bent down to take something off her shoes. Being a nosey bugger i approached her and asked her what she was doing. She showed me these very strange contraptions called Yak Trax, and told me buying them was the best money she had ever spent!
I have someone very dear to me who has gone arse over tit on numerous occasions over the last couple of weeks whilst on their way to work wearing leather soled shoes. These Yak Trax can be worn over any shoes and will give you the confidence to walk on icy surfaces, just remember to take them off when you go indoors!
