I'm looking for a pair of stylish running shoes and want to know if such a thing exists? I am a regular runner, and normally do between 5-10km runs a couple of times a week in Nike or Asics proper running shoes. But I travel a lot for work and try to only bring my carry on. I'm looking for a trainer that looks fairly smart and I could wear in the evening or to travel in, but is suitable for an occasional 5-10km run. Any advice would be great!
