Query: Moab Ventilators by Merrell

I have worn this style of Merrell shoe for 10 years - probably 10 pair. This pair ran at least 1/2 size small and the toe box is nowhere as roomy as the prior pairs. I imagine it is a function of the Chinese taking over production. Unfortunately, I didn't believe what my feet were telling me for a week. I now will be donating this pair to Goodwill rather than sending them back for an exchange.No more Merrells for me through the mail.
