Can anyone tell me exactly what is slip-on shoes ? I'm looking to get a pair of sneakers that doesn't need to have laces on it, are those called slip-ons ?

For example, is this slip-on from Onitsuka considered a laceless shoes ?

Shoes

Slip-ons are typically low, lace-less shoes. The style which is most commonly seen, known as a loafer, slippers, or penny loafers in American culture, has a moccasin construction.

So then why are there sneakers called slip-ons ? It also simply means that do not need to have laces on ?
