In reply to UKC/UKH Gear: I would say the fit of the Ribelles, assuming that the Goretex version is the same as my unlined pair, is true to the sizing for Scarpa boots but is much more roomy than the equivalent size in a normal running shoe (on or off road). I take a size 7 / 41 which in running shoes by ASICS, Inov8, Hoka and Montrail, to name just a few of the brands I’ve used in the past, means a close, comfortable fit with just a thin running sock.
With the Ribelles I can wear the same sock under a mid-weight pair of Sealskinz waterproof socks and they still feel as if there’s a bit of free space in reserve, ie I have to pull the laces up fairly tight despite the bulk of sock.
