'delayed for quite a long time' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'oh ruins footwear for repair' is the wordplay.
'for repair' indicates an anagram (the letters must be fixed).
'oh'+'ruins'+'footwear'='ohruinsfootwear'
'ohruinsfootwear' with letters rearranged gives 'WAITS FOR ONE HOUR'.

'is' is the link.
