Greyder is a Turkish brand. Somehow Greyder shoes sold in Turkey is low quality, I didn’t like any of the shoes. It make me disappointed as a Turkish myself and I felt like I throw away my money. The desings of shoes are okay but the metarials the shoes made out of is not quality. Comfort is a important thing that you look first in shoes but Greyder boots are far from being comfortable but nice thing about this shoes is it doesn’t make your feet sweat which is nice and protect your from bacteria. If you buy the right shoe size of Greyder flats, it is going to be small for you and if you buy one size bigger of the flats it is going to be way too big for your feet. Another weird thing is about this brand is, different color of same shoes have different prices. I don’t recommend this brand at all.
