This is the second time I've bought these shoes and can you believe this is the second time the size chart doesn't help? They are too big, I usually take 6 and the first time I ordered 6 and the second time I hesitated between 5.5 and 5, finally I decided on 5 (absolutely sure they fit perfectly this time since I got a 6), but no, they are too big AGAIN. I measured my foot and it was 23cm long, the chart says these 5 were 23cm long. I don't know what tape measure or ruler they use because they are not 23cm long. You need to update your chart or make it more accurate. adidas. It's ridiculously stupid to order the same sneakers twice and not be able to use them!
