Very soft sole, comfortable upper, flexible heel and low weight. Stable but easy to turn on and off. Ventilation is limited, but you can't be waterproof and ventilated at the same time. I've tried several brands over the last few years, D (leather, hard, heavy and sore upper), M (comfortable but a bit heavy, not waterproof), S (wood and hard sole, expensive), C (rubber, waterproof, comfortable but thin like flat shoes). All had their pros and cons, but most of all I am satisfied with this purchase. I can't comment on durability as I've only been using it for a week.
