I agree with Kyle
I bought mine last february and have worn them on average 3 or 4 times a week since then in all weather conditions. They grip well on all surfaces, grass, mud, astroturf, gravel, sand... even on the slippery bluebells at N v S! I chuck them in the washing machine at the end of the day and they come out like new. Buy yourself a pair is my advice. I shall certainly get another pair when mine wear out
