I bought the boots because I was working at a Donkey Sanctuary and needed to wear steel toe caps. The boots are leather with a rubber sole. They are great for general farm work and have a heel so you can also ride in them. I got the black ones because my chaps are black too. They also do half sizes which is a bonus. They cost £24.99, reduced from £39.99.
As they are leather they have worn in really well and are very comfy. The sole is also comfy. The only slight problem is that as they are jodhpur boots with the elastic section on the side, water can come in. They also have good grip underneath.
I don't really know much about the brand K*TY. On the equestrian clearance website is says it is a brand "where quality meets affordability". They have a wide range of products including rugs, jodhpurs, gloves etc.
All in all they are very good boots and as long as you are not walking in water or mud then they are great and very good value for money!
