I ordered these online from Zappos and got them within a few days. These shoes were used in the Mexican 68' Olympics. After lacing them up, they fit really well but were slightly too long. These shoes have almost no support though, so if you have large arches, these may not be very comfortable for you. But, if you're like me with flat feet, they are amazing. They feel like a sporty pair of slippers, light and comfortable.
They have good grip, but it seems to wear out quite quickly. I've had these for awhile and they haven't shown any signs of wear yet even though I bike to campus every day with them.
Conclusion: If you have flat feet and want an amazing shoe that's stylish, comfortable, and great for sports, get this shoe.
