I think she likely will pick someone up sometime soon, but as I go through potential companies, I can't tell who might. Nike.. maybe, but I don't see the upside for them, especially if Cranny is beating her later on.
Adidas might be seen as picking up scraps from their biggest competitor, so probably not. I don't think she fits the vibe of the current athletes for either New Balance, ON, Puma, Hoka, or Brooks - she's likely not running happy. Maybe if she wants to move to the roads and replace Sara Hall for them, maaaybe I would say ASICS, though they sponsor so few people I can't see it happening.
This might be a long shot but I'm just saying it to look like a genius if it happens. I think KIPRUN gets her. Doesn't have the baggage, barely has a foothold here since they are not American. New brand who wants to be seen as serious performance-wise so they will get someone who gets results even if they are not very personable.
