Spiked, unlike velcro shoes? (5)
I believe the answer is:
laced
'spiked' is the definition.
(synonyms)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for laced that I've seen before include "with extra spirit" , "Added alcohol to (drink)" , "Administered a beating" , "Served with alcohol or a drug added" , "Intertwined" .)
