For sure! How to wash them depends on the materials. Many summer shoes made with light textiles are machine washable nowadays, but they must always be washed separately, in a short program, and at a low temperature. And dried in room heat in a well-ventilated space. Leather shoes should be washed by hand with soap and a sponge intended for leather. In most cases, it is enough for leather shoes to brush loose sand off the surface and wipe the surface with a damp rag. Waterproof textile shoes should be washed by hand, and take into account that they take a long time to dry.
