After trying Barefoot style shoes (which usually have much wider than normal toeboxes) I can never go back.
Vivobarefoot shoes are expensive, but pretty high quality and have a great toebox.
Freet are more affordable and often made of recycled material, but some of their designs can be slightly odd looking. They hold up well though, very nice quality from the reviews I've seen. They're made in the UK, I believe.
Splay shoes offer what is essentially wide toebox vans.
There's tons more though. I'd recommend Anya's Reviews to narrow down what suits you best, she's pretty legit in her info from what I've seen.
