Does anyone happen to have a pair of either of these Merrell boots? I've bought a pair of Oslos but am not too sure about them and am curious to know how the Winterbelle Peak or Natalya compare. I prefer the higher legs on the latter two and also the boot designs, but am not sure about relative warmth and waterproofness. I basically want the warmth of my sheepskin-lined boots, but waterproof and with better grip in the winter!
