My son adores these boots! I wasn't sure I would be able to find everything he wanted in one boot: he wanted slip-ons, not too high up the calf, waterproof, (and per Mama, warm as we live in northern Minnesota), and comfortable. These tick every box!!! The slip on and off, they're completely waterproof, comfortable enough to wear all day, and rates to 45 below zero. He does report they keep his tootsies dry and warm all day! Amazing find and since hell be able to wear them for several winters, the price is very affordable.
