Here a short abstract of the paper: "The Rebel Pro are a radical rethink on winter climbing boots, being far lighter but more dexterous and precise for climbing than any traditional alpine boots. They are lightly insulated and completely waterproofed with Gore-Tex® (in the form of in effect a sealed inner sock of Gore-Tex ICF - Insulated Comfort Footwear) to keep your feet both dry and warm. Whilst a good fit is very much dependent on the shape of the wearer’s feet, for many the fit is snug and very supportive with a good heel hold. This is due to the ‘Sock-Fit’ and the new NAG last (also specifically developed by Ueli Steck) and a graduated carbon midsole which gives outstanding precision and sensitivity on mixed and delicate terrain."
More positive feedback are coming from Ian Parnell, Climb's Associated Editor, who tested the product during the last BMC International Winter Climbing Meet, that took place from the 26th of January to the 2nd of February in Scotland. Parnell, well known for being pretty handy on mixed and delicate winter terrain, said that "these are by far the lightest winter boots I’ve used and as a result were a real help with the precise footwork needed on things like Centurion that I climbed that week. They also held up well to the deep snow trail breaking we had to do, keeping my toes surprisingly warm for boots of this weight. It would be interesting to see how they fared in the Alps in winter, but for Scotland they are perfect."
