The glyph right shoe is a an oval missing its left side (resembling the top-down view of a horseshoe pointing to the right) represented by the Unicode character ⊃, "superset of". The right shoe has several uses in various dialects:
- In SHARP APL, <source lang=apl inline>⊃</syntaxhighlight> is Nest when monadic and Link when dyadic.
- In APL2, NARS2000, GNU APL, and APLX, <source lang=apl inline>⊃</syntaxhighlight> is Mix when monadic.
- In Dyalog APL, dzaima/APL, and ngn/apl, <source lang=apl inline>⊃</syntaxhighlight> is First when monadic.
- In A+, <source lang=apl inline>⊃</syntaxhighlight> is Raze when monadic.
- In all nested APLs as well as A+, <source lang=apl inline>⊃</syntaxhighlight> is Pick when dyadic.
- In NARS2000, <source lang=apl inline>⊃</syntaxhighlight> becomes Superset when used dyadically as operand of the Multiset operator (<source lang=apl inline>⍦</syntaxhighlight>).
In the context of nested APLs, monadic <source lang=apl inline>⊃</syntaxhighlight> is often called Disclose in symmetry of <source lang=apl inline>⊂</syntaxhighlight> (Left Shoe) being Enclose. However, as this name is ambiguous, the names First and Mix are to be preferred.
