I wear standard 8.5 cm men's shoes My feet have been the same size for 52 years and I've only worn Merrell shoes for two decades. Why? Consequence. Because they always fit and always sit like they were made to order. This pair was so snug I couldn't get my foot in the shoe and they were a good inch longer from heel to toe than the 8.5 Jungle Moc I was wearing. wear. Strange. Small.
