It took me two try's to re-size these shoes appropriately, but I am glad I sent them back. I normally wear about a 9.5-10 in street shoes and I downsized to an 8.5 or size 41. After about 4 days of climbing in them the shoes felt snug and comfortable. I have had them for about 2 years now and have had them resoled twice. The Solutions edge well, and the toe box is great in my opinion. The sensitivity of these shoes is also wonderful. I can feel everything my feet touch, almost as if I wasn't wearing shoes. Overall, I am very pleased with these shoes. I would recommend them as more of an outdoor shoe, but in any environment they perform brilliantly.
