It looks and feels premium, and fits perfectly. Therefor I am ordering the 2nd pair with in black color more suitable for office :) They have a fairly deep tread, and they nicely grip even a highly polished linoleum-covered floor. The leather is soft and comfortable from the first wear (no "breaking them in", rubbing or blisters). Might be fine if they were just walking on the beach but not great for in water. The entire job took approximately 25 minutes. if you can ignore the sharp scratching on the right toe. 30min, combinado con su larga duración a mi se me hace más optimo cargarlo por periodos de 10 a 20min cuando no lo estoy usando y mantenerlo en el rango de 30%-80%. If they were of better quality I would give this product a better rating. If you can afford it pay for the battery powered one.
