I've been using the same chromed MKS clips for most of my riding, about 75% of it as a fixed gear, over the last 9.5 years.

I've dragged them a little bit, even smashed the tip of the clips on the ground a few times. It can be difficult sometimes riding fixed gear to get your foot in before the first revolution, so this style of riding may be more difficult on the clips and straps.

Only now, after nearly 10 years, am I thinking about replacing that set of clips. The right one, the foot that I remove when I stop at lights and such, is finally showing some wear and speckles of rust through the chrome.
