I currently have the Head Raptor 140 RS which is my favorite boot I have ever owned. A local shop has the Head Raptor 140 S Pro at a great price and I'm thinking of getting them for when my 140 RS boots need replaced. I tried them on and they feel identical to the 140 RS. Other than the color they look and feel the same. Can anyone tell me what the differences are? Although I do like the white much better than the grey/black color.
