OK. First be aware, I have yet to depart for the CF, but have done some serious walking/hiking to check gear and to get in better shape. Sharing the early "mon pieds du Camino" saga, I first purchased Salomon 4 GTX 2's in my regular shoe size and added the Orange Insoles. (No, this is not an advert.) The boots are lightweight and waterproof Gortex. Pretty pricey this combination, but believe it not a place to skimp. As many others have said, everyone is different and with extended walking, (in various conditions,) my feet have grown larger, so the uncomfortable boots were returned for the next larger size. Now I wear Thorlo's with a liner and am glad to report true comfort and no blisters. Of course this is the combination which works for me, and the rigors of the
Camino Frances will be the "proof of the pudding." While my goal is to loose 4o more pounds before departure, right now I am 6' 1" and 250 pounds, so tough on my "inexperienced" feet, but pleased with the current results.
