I had them as well and took them off. I liked being closer to the ground in order to get my feet planted when stopped. Did't like the ride and bottoming when riding 2 up even at just 1 inch. Rear end just felt "gitchy".
Took them off, lowerd my seat (had gel pad inserted while it was apart) and got boots with thicker soles.
The real solution was to go to a parking lot with the "Ride Like a Pro" exercises and increased skill and confidence at low speed. Still need to pay attention and use caution but I am OK not to be flat footed anymore.
Guess you can tell that I am vertically challanged (insert short ass here).
