I am a supinator, male, 11 stone and find this shoe keeps me injury free and comfortable. It is a little on the heavy side, struggles in really muddy terrain, but is excellent in dry conditions. I have used mine on the Atlantic Coast Challenge and in various Endurance Life halfs and full marathons. I have had no problems with them when they are wet, after running through streams etc., although you have to be careful of a little side slip within the shoe on sloping ground. I am sure there are better shoes, but these are great value for money.
