In 2007 and 2008 LRC had some articles about Spiras.
Supposedly they were unofficially banned because they had springs in them.
1) Are they still unofficially banned?
2) Could a runner win in these shoes and not get challenged?
3) Do Newton shoes also have a spring in them? If so, why no controversy with the Newton shoes?
Guys ran in the Olympics in them. They are not banned in any way.
I had a pair that I used when I was recovering from a foot injury and surgery. They are incredibly padded and soft and I needed that extra level of cushion as my foot got stronger. Once I no longer needed them I stopped running in them. They felt heavy and clunky.
Spire stopped paying guys to front-run at big city marathons. Now nobody talks about them.
they have partnered with Duck Dynasty and are talking about walking shoes. Looks like they've moved from the high performance focus to the day to day. Makes sense for folks on their feet all day I guess.
Saw 'em at an expo once, but didn't try em on. Just seemed strange.
