I've had these for 3 years (2018). I only wear them on a sailboat (about 500 hours total). Grip was good on wet deck. However, the laces began to wear out almost immediately and eventually broke. Unfortunately, the laces are woven in and out on the sides of the shoe and sewn inside behind the heel. I replaced them with short ones that don't wrap around the back of the shoe, but that means the decorative(?) lacing on the side had to be cut off. For 110€ I would have expected much more durability.
