Loafer and sneaker are overlapping seller labels
The title uses both terms for this one pair; it does not describe two interchangeable designs. The useful identified feature is slip-on entry. Compare how the opening admits the foot and how the upper retains it afterward, rather than treating the casual appearance as proof of athletic performance.
A cluster of sizes, not separate recommendations
The black 10.5 and 11 links provide adjacent sizes with closely matching descriptions. Start with the length that suits your foot, then check whether the slip-on upper holds it during a turn. More length is a poor solution when the real difficulty is getting through the opening.
