My Mistral airflow trainers are as brilliant as I hoped they would be. I first saw them on holiday in Italy and thought they looked great. Following some googleing on my return I bought a pair and they are soo comfortable no wearing in required. The only negative I would say is small stones can collect in the air holes on the soles. Lucky for me my husband had a Swiss army knife with a suitable attachment that did the job. A tool could be a good idea to accompany the shoes. I didn't wear them in water on this occasion, the air certainly flowed to keep my feet comfortable
