I have not bought shoes at H&M in ages but these 3 flats tick quite a few boxes for ideal summer wear: the white fabric ones are perfect under jeans, the maroon slides with the different shaped straps would liven up any plain black outfit and the black suede with the tiny heel are both pretty and comfortable enough to wear for a night out.

White fabric cross-over slides, maroon strappy sandals and black suede flats, all at H&M
