There are lots of good places to think about trying when you want to buy women's leather trainers. One place I always recommend to friends, though, is a brand called Cocorose. The quality of their stuff is beyond reproach, with a real focus on using supple leathers that fit around the foot instead of digging into it. Also, they are big on removing seams, with minimal seams reducing things like your shoes digging into your foot as you walk around.
I have always recommended this brand to friends and family because I have bought many pairs. I have never had an issue with my shoes' delivery or quality, making them a great brand to buy from. The designs are nice and fresh, too, offering a nice break away from the usual generic styles that most tend to go for. They are worth investigating, for sure!
