Personally I wouldn't buy the Rhinegold ones (the estalon link goes to the same place so cant comment on those).
I have the Rhinegold boots and also the Weatherbeeta ones (with fleecy lining) - both similar price but the WB ones are 100 times better. The Rhinegold ones slip a little bit and also my horses legs sweat a bit in them as they have shiny slippy inner material. They dont fit that well, being rigid and bulky. I got them after the WB's yet they look more worn and old.
Definately recommend the WB's. Can find them on Ebay here:
