With water I did not care much, but the Mares booties are perfect minimal shoes for outdoors. Jogging and walking, wherever I no longer barefoot come, the Mares are ideal. The sole is very non-slip, the booties fit like a second skin and with the appropriate foot training is also a trekking rucksack on his back go well with them. Mud and marsh passages are then no longer where I had earlier evade troublesome problem, it is now easy through. Have taken on the general recommendation here a number of small and they fit perfectly.
