I originally got mine to help me with ascents and descents on the hill, to assist my knees, but I found that they help in other ways too. By using other muscles (other than just your legs) to assist with going up or down a hill, you can reduce the fatigue in your legs, although conversely there may be additional fatigue in your arms, but not enough to stop you walking, its just like a re-balancing of the load.
Walking across streams is easier with them too, or across most rocky environments, its like having a rail or post to hold onto (albeit that the rail / post can move). Just helps with balance more.
In terms of performance, on the flat you can also use them to increase your pace by pushing backwards with them to help propel you forwards.
My knees have improved since I bought them, and I probably don't rely on them as much nowadays, but I know that they are helpful for longer treks or climbs / descents.
