After much debate with myself, I bought an expensive pair of Montrail walking shoes at REI. They fit well, feel great, and my back and legs don't hurt while I walk or afterward. Sounds great!! BUT... my middle two toes on my left foot go tingly when I wear them. I don't understand! They fit well, and the next half size up was obviously too big and the arch was in the wrong place. I loosened the laces, don't know what else to try. Taking them back is an option, but will be problematic at this point, not the least because I've obviously worn them outdoors. REI is not close by for me. And here I've finally found shoes that are constructed so I can walk without back pain, and my silly toe goes numb. Suggestions? Maybe a technique to re-lace them? Or anything else? I'd like to keep them if at all possible. Thanks, Beth.
