What shoes should I wear to travel to Eastern Europe in summer?

Good air permeability and non-slip shoes.

1, breathability: walking is easy to sweat, shoes must be very breathable, mesh shoes on the market and online are more breathable than leather and cloth, and mesh shoes are the first choice.

2, non-slip: it is inevitable to climb high and low when traveling. It is very dangerous that the sole does not slip, and the anti-slip of shoes can not be ignored.
