Vibram Five Fingers Sprint Water Shoe - Very lightweight, has rubber sole that could be worn for any type of activity...I wouldn't limit to just water fun! Sized as Womens 41 - Chart shows this is US 8.5 to 9 EUC- Only slight wear visible on soles Shoes are done in shades of green and I would call the Velcro straps gray. Velcro adjustable straps on top and back of shoes. These shoes seem very light and comfortable! If they were my size, I'd be keeping them! Would look great with an olive green cropped hiking pant! Note: I do not own a pair of these myself, so I can't speak to how they run size wise. Measuring from the tip of the big toe to the end of the sole is approx. 10.5" Visit my closet and check out my other great listings! New listings daily!
