I have been using True Linkswear ball golf shoes for this very reason. They are spikeless and originally built on a barefoot/zero-drop platform. I still say the ones I have are the best fitting shoe I have ever owned. Unfortunately, the company has gotten away from shoes that are actually in the shape of the foot and gone toward more traditional shoe design. In other words, they abandoned what made them great and are now just another shoe that no longer fits me.
I like the idea of the Vivobarefoot shoes, but they are a bit too expensive for disc golf. The sole is just not going to hold up and can't justify having to replace them at the cost as often as I would need. But if someone like Merrell or Keen were to design a shoe with a footshaped toe box and a heavy duty sole, I would be all over it. We should all be wearing "clownshoes". The foot does not come to a point. Look at opened toe shoes like flipflops or Birkenstocks. They are round and shaped to follow the natural shape of the toes. If most people could see how their toes are scrunched inside the vast majority of shoes, they would not accept how the shoes are designed. But people just can't get over the "weird" look to a shoe properly designed to fit a human foot. Oh well, end of rant.
