This chunky classic boots doesn’t have a zipper by the sides. Technically, You wear it by pulling it upwards. The leather is soft making pulling much easier. It was weird for me in the beginning but now it is easy wearing. It has a fleeced lining on the inside part making it comfortable and warm on the legs and feet. I can wear it without wearing socks and my feet doesn’t feel cold. It’s very long and covers the leg from the knee part. It’s not heavy and it makes walking easier. It’s a short heel and not high heel. Because it’s padded with fleece thermal lining, I sized up. I usually wear a size 39 but I ordered size 40 so I can wear a socks in it. It fits perfectly. It was a good decision I made after reading the reviews on here. Delivery was very fast. I highly recommend 👍 Good boots for winter season. Great quality material! Great purchase! Great value for money. Don’t hesitate to buy.
