Looking for a reliable comfortable pair of flats that do not get worn easily for work

I keep buying cheap $30-40 flats 🥿 like that emoji for work but they keep getting worn so I have to toss them every couple months, I thought buying a branded pair of Michael kors flats would last longer but they also cost $200-300 and got worn down the same amount of time. What is a good pair of black flats that will support the foot and not cause blisters on the toes and also last long? Links appreciated. Thank you!!
