I've had a pair of Treksports for about a month now, and definitely enjoy them. I never had a problem with foot or any muscle aches and pains from wearing these, and they were pretty comfortable right out of the box. I'd compare wearing these to having gloves on your feet. The nice thing about Treksports is they combine the breathability of the KSO with the treads of the Trek. The sole is thin enough that you feel every contour of uneven ground, but thick enough that stepping on a stone or something sharp is not painful. The grip with these shoes is terrific.
A few minor inconveniences and issues:
- Watch where you are walking. There is no padding between your actual toe and the end of the shoe, so stubbing a toe is quite painful. I haven't actually dislocated or broken anything, as I read in this thread somewhere.
- Smell - can become an issue. The shoes are machine washable, however. I've washed them once and they came out very clean, though they smell again a few days later. Nothing too bad, though. Be sure not to put them in the dryer, as the heat will melt the glues that hold the materials together.
- Wildflowers/weeds/grass: Some courses with tall grass with seeds, or flowering plants can sometimes be annoying to walk through. When you walk through this type of habitat, flowers and seeds tend to get caught between the toes. While not uncomfortable, it's more of an annoyance to feel these between your toes, or to look down and see a collection of flowers, etc.
Can't say these shoes have helped my disc golf game, but I'm relatively new and vast improvements here will take time.
Overall the joy of wearing these shoes overwhelmingly overshadows any of the minor inconveniences with wearing something so unusual. I love my shoes and would recommend them to any person who enjoys the outdoors.
