Dynafit Alpine Trail Running Shoe - M 10.5 - Like New

Just bought these here on poshmark, but they are a half size too small. I took them for a walk around the block with my dog hoping they might be able to work, but I know if I don’t get the next size up I’ll be kicking myself. They are for sale on backcountry for 67.48$ so that’s what I’m asking. Please be reasonable.
