I purchased ICESPIKE at the beginning of 2012 after taking my young puppy for a walk and ended up doing a bad audition of dancing on ice! The weather improved so I could not do a true test. The return of bad weather this week Dec 2012 prompted me to get my ICESPIKE out again. Result - excellent grip! I tried it on compact snow, glassy ice, ice with a layer of water, cleaned footpaths and roads. I have ICESPIKE in a dedicated pair of winter boots (for dog walking) and I also have a pair of ICEtrekkers Diamond Grip for use when I go somewhere that needs me to remove my grips for indoors e.g going to the shopping centre. My dog now wonders how I manage to keep up with him! 10 out of 10. Excellent products and great service from www.icegripper.co.uk
