Buzz 5i Mixed Media Platform Sneaker

I got these shoes bought for me as a Christmas present, and for the past 3 months I have worn them so much, but they cause a lot of physical problems. I'm 17, and wear Dr. Martens very frequently (3 other pairs) but none have made my knees or legs as sore as the Buzz I's, particularly because of the weight of them. They are extremely heavy, like more than 1.5kg each, and the height on them is more than two inches. Even when sitting, I find they prop my legs up rather high, and cause knee pain, and particularly in my ankles too when walking around, because they are so so so heavy! I am also tall at 5'11, so big or heavy shoes dont normally cause much pain, but these ones are definitely more for shorter outings. They are beautiful and my favourite shoes, but please dont overwear them! and dont waste too much money unless they are discounted!
