Where can I get a pair of flipflops or sandals in Hanoi?
Summer is the golden time of flip flops and sandals in general. The scorching weather prevents many people from wearing shoes; moreover flip flops/sandals are so much convenient to take off before entering some café, restaurants or even pagodas. There are two biggest places for this product, one is Le Duan Street and the other is Hang Dau Street.
As Le Duan Street mainly provides working clothes, like rubber boots, rain coat, security uniforms, flip flop/sandals are not their major products. The positive features are low price and durability, but the styles are limited and the design is quite rough (imagine Birkenstock and the likes).
Hang Dau has a better diversity of styles, colors and designs, and the prices are just slightly higher. Shops here also sell bamboo flip flops, which are very stylish in this hot weather, and high quality leather sandals, sometimes imported from Korean or Japan. You really should go outside and get one pair for your own.
