If you want to keep your sneakers from creasing then you have to use them carefully. That is the smartest and most foolproof way of preventing disfiguring creases. You can also try stuffing them with some newspaper at the toe. This will kill two birds with a single stone since not only will your sneakers remain crease free but the newspaper will also absorb the stinky foot odour.
Always remember to keep your sneakers clean. You can clean them regularly with some shoe cleaner. If you want you can even put them in your washing machine with a normal quantity of detergent and a generous amount of bleach to keep them squeaky clean. In addition most people recommend that you keep two pairs of sneakers handy one pair for sports and hikes and another for going out and all.
