What an answer looks like
Verbatim openings, exactly as the assistant wrote them.
Based on current reviews, several standout options exist depending on your priorities: Overall top pick: Nike Vomero Premium/Plus – This has emerged as a consensus favorite. The best cushioned running shoes tested by RTINGS.com are the Nike Vomero Premium , with an impressive heel stack height.
For bad knees, prioritize shock absorption + stability + the right fit—not just the softest shoe. If pain is persistent, sharp, one-sided, or worsening, get assessed by a PT/podiatrist; shoes can help comfort but won’t fix every cause.

How this was measured
On October 8, 2026 we asked Claude, Gemini, ChatGPT, Perplexity 10 questions about running shoes that name no brand, and 4 that ask for a choice between Nike and On. Each question was asked of each assistant several times, through its official interface for developers, with a live web search on every ask. An answer that did not search was not counted.
A brand counts as named when an answer names it or one of its products. This measures how often each brand comes up in AI answers. It does not measure which brand is better, and it is a reading from one day: answers change.
