I had the Muck boots, think they were called Tay, I hadn't them long, so the soles were not worn, going down a slope of wet grass, feet just went from me, grabbed a fence to break my fall, ended up in A&E four stitches in my finger.
What was worse, I emailed Muck Boots telling them what happened and they need to have a look at their soles of their boots, I never received an answer.
