Fixing a rubber slippers whose front part was cut while playing would depend on the materials available at one's disposal.
The cut part of the slippers can be gummed to the rest of the slippers if a suitable gum is available. However, care must be taken to make sure that the cut part aligns with the original space where it detached from.
The cut part can also be fixed using a needle and thread assuming one has the relevant skills and the materials are available.
However, since only a piece of safety pin seen on the sidewalk is available to work with in this case, the most logical thing would be to find a way to use the pin to attach the cut part to the rest of the slippers via the the original space it detached from. This might not be the lasting solution, but the slippers might serve until a more lasting solution is obtained.
