I watched a video of someone taking a spill. One of the first things to happen was their tennis shoe came off. For the rest of the slide, it was their sock providing "protection". You can imagine how effective that was.
I have been buying my Response Gear boots from Big 5 Sporting Goods. They have some decent work boots for a low cost. Some of the soles are better than others for traction on wet pavement. I looked at motorcycle boots before buying the last pair, but couldn't see the value in them. The design looks like I belong on a race track, and I didn't want to look wierd or carry extra shoes. It didn't seem like the protection was any better either. Work boots are about 8 inches high. They don't have the ankle pad, but chances are that little pad that seems about as big as a silver dollar won't do much to protect the ankle either. The shin pad seemed like it could easily move the point of fracture above the pad too. So I wasn't convinced this was the way to go. And normal looking motorcycle boots seemed like they would be loose above the ankle and not give as much support.
I ended up buying some Magnum boots off the Magnum online store. They had a sale on a high top work boot that was also waterproof. The soles have great grip, and they are comfortable. It will be interesting to see how they work out, but for now, I am very happy with them.
