Is the word pés the same in Brazilian and European Portuguese?

Yes

The spelling, meaning, and grammatical category (masculine plural noun) of the word "pés" are identical in both Brazilian and Continental Portuguese. The only difference lies in pronunciation and prosody. While the vowel sound is generally an open /ɛ/ in both varieties, the phonetic realization and the rhythm (stress and cadence) of the word change depending on the surrounding words and the specific accent of the speaker. In Continental Portuguese, the reduction of unstressed vowels in a sentence often affects how "pés" is heard in context compared to the more melodic and vowel-heavy rhythm of Brazilian Portuguese.

Brazilian Portuguese Examples

3. Eu estou com os pés muito gelados. (My feet are very cold.)
