I love a good Classic for ground feel, but for what you are doing Treksports would be great and they dry fast. There is this guy on the boards with those orange Treksports and he is doing what you are doing and he lives in England. He posted beautiful pictures of his hikes in the English countryside in a ghost village but I can't find his thread anymore, just this one: (http://birthdayshoes.com/forum/birthdayshoes-com-general-discussion/treksport-in-orange/)
It's all about conditioning. I spent 5 hours in the Narrows in Utah in Flows, and 8 hours in the Grand Canyon in Treksports without any problems. So they are NOT only for light hiking in my case. I was actually going twice as fast as the guide in the Canyon, and he had hiking boots. If I had not worked up to it before hand it would have been difficult though.
Spyridons, Treksports and Komodosports are all good options for you, even Bikilas would work. It all depends on whether you need more traction (Treksports and Spyridons) or more ground feel (Bikilas and Komodos), but all of those have enough protection for your activities. The first 2 options may be a bit thick for martial arts though and just walking around, so you may want to stick with the 2 others.
Went scuba diving Saturday, had my Flows on while on the boat to get to the dive site, and of course they were perfect. Had my Mauve Classics and Slate Sprints on for the rest of the weekend in Kingston Ontario.
I agree that you don't HAVE to run, but if you have an interest in it and are willing to go through the transtion for a long period possibly ( strenghtening the feet and finding your form) it can be an exhilirating sport. It's my favorite, and when you get good at it quite easy (it's my vacation from other more strenuous workouts). The sceneries you get to discover on the way can be great, instead of looking at an instructor for an hour. I do yoga, the Insanity DVD's and other stuff as well, but running is fabulous. It's worth pushing through.
All my kids wear them to school, but my 14 year old son ran track this past year, and they forced him to wear coffin uni-toed shoes. His mile time was quite impressive with vff's, but their draconian ideals of making him wear "regular" shoes immediately added 30 seconds to his mile time. Now, he is experiencing hip trouble from those regular shoes. All of my kiddos love them and love wearing them to school.
That is so unacceptable. Those closed minded morons will destroy his hips, and who knows what else, just for the sake of conformity.... terrible.
