I've regularly used sandals for both commuting, day trips, and touring for about 12 years. I'd guess I have ridden about 40,000 miles with them during this time. I have gone through Shimano and Lake sandals in the process. I have never found that the top of my feet have been in any excessive danger, even on occasional spills. They are great to wear for touring, as it makes life very comfortable off the saddle. They also do not stink up the tent nearly as much as shoes and dry up much quicker. They additionally do not require you to wear socks and create wild tan lines on the feet. Finally, they can frequently help start a conversation with inquiring minds. The only downsides are: (1) potential hot points on the feet on long rides and (2) extra care needs to be given to them when it gets cold outside. I do not wear the sandals in winter months anymore. I wish that Shimano would resell their original model again.
