I'd had problems with painful plantar fasciitis for over 5 months but was reluctant to miss a planned trip that included at least 4 hours of walking daily over some rough and wet terrain. I'd tried very expensive custom orthotics and specialty insoles in other shoes with no success. I ordered the Siren Sport GTX shoes because of the wide width, Q-form design, and waterproofing. For extra heel cushioning, I added simple Dr. Scholl heel pads and wore hiking socks with arch support. I found I was able to walk well even with a backpack. The shoes don't make airport security scanners beep and I didn't have to remove them at airports in South America. I was able to climb the uneven steps of Manchu Picchu, stay comfortable in the wet Amazon jungle, stay steady over slippery coastal rock, and keep my footing on uneven lava rock in the Galapagos Islands. The side-stitching did fray a little from contact with jagged rock, but the shoes are still in great shape after more than a month of rugged wear. Though I tried other brands of walking shoes, my Merrell shoes are the most comfortable and supportive footwear I have now. It would be nice if Merrell added more wide-width women's items to the line. I'm wearing the shoes for urban hiking now (dog-walking and city shopping) and plan to use them in the ice and snow of a Canadian winter. Thanks for making these shoes--they saved my trip.
