I was somewhat put off by the price on the day of purchase, but these well designed cleats happened to arrive during an unrelenting series of ice storms, during which they more than proved their worth. Easy to put on and take off, easy to transport, and far less likely to dislodge than other cleats I have tried, these immediately and forever have ended the series of humiliating pratfalls I had been taking on the way from my car to my back door, on thrice-a-day dog walks, and on at least two serious treks through terrible weather over very slick and unforgiving surfaces in the deep rural countryside. I am more than pleased.
