适合你水平的解释：

This phrase has two meanings. It means someone runs fast, or it means food goes bad quickly.
You can use this to describe a person who is a fast runner. You can also use it for food that spoils quickly, like fish or milk.
This idiom is versatile. In sports, it describes speed. In the kitchen, it acts as a warning that an item is highly perishable and should be consumed promptly.
The phrase demonstrates a metaphorical extension where 'speed' (速い) is applied to the degradation process of organic matter, highlighting the cultural importance of freshness in Japanese culinary practices.
This idiom serves as a prime example of semantic polysemy in Japanese. It bridges the gap between physical kinetic ability and the temporal decay of perishable goods, reflecting a linguistic focus on the 'movement' of quality.
From a cognitive linguistics perspective, '足が速い' utilizes the 'Time is Motion' metaphor. By attributing 'speed' to food, the speaker conceptualizes the rapid loss of freshness as an active, fleeing state, which is a common trope in Japanese idiomatic expressions regarding food safety.
