### Clue: Revolutionary shoe is too tight to accommodate foot (7)
### Answer: TOOTSIE 
 ### Explanation: Definition: foot
A hidden ('to accommodate') reversed ('revolutionary') answer in 'sho**E IS TOO T**ight'. I would have defined TOOTSIE as a toe, but Chambers gives 'foot' also – and suggests the derivation as a childish version of the word foot.
