Hi Trekkie,i have no experience of these,but agree with Minty`s concerns.I would recommend khatoola micro spikes,that are fit for purpose,but around £50.What price do you put on broken limbs or Mountain rescue call out<img src='theme/emoticon_smile.png' />

I too recommend the above ..Khatoola (made in America ) used them for three years now in the fells ....there the business for `walking ` in ice bound sreas on slopes , tricky stuff(talking in the hills here , not just getting around to Asda). You can put them in a small bag in your rucksack , pull em out , pull over your boots (they have proper spike and chain links , like crampons , I call them crampets ! ) Were £40 when I bought them , I`ve been out in some proper snow and ice bound fell walks with them ....brill.

i had some that stretched across your shoes which worke dreally well on solid ice. if you get snow or slush they tend to get pulled off. i have just bought some more but with an extra strap across the top of the shoe. I have only used them for walking the dog in town so i cant really comment about rough and changeable terrain
