This shoe fits well, I'm a size 9 and I'm a size 9 and it fits perfectly. I always like a little wiggle room for my toes. Excellent waterproof performance, I used it for my day trip to Muir Woods the day after Thanksgiving and it rained all day (thank goodness the rain pushed out the smoke from the campfire) and my feet were dry and warm. I use hiking shoes for all my hikes and just switch to this shoe and it works well. I rode it 9 miles. this shoe is light, waterproof and has a good grip
