My teenage daughter needs some strong durable boots, which are waterproof, for a long walk to college and back during the winter and a trip to Vienna. NOT hiking boots or the things you see in outdoor shops! They have to be fashionable or she won't wear them!! All the stylish boots we've looked at are hopeless for any sort of heavy wear. Can anyone recommend something please? Budget of up to £70 (though would like to pay a lot less!). Thanks
