I bought these to replace a pair of worn-out Mizuno trail running shoes.  The Mizunos were size 12 and I bought size 12 in Asics, too.  The Asics seemed just a tad narrower but that could have been just because they are new.  I've been using them for daily wear as well as running and they feel great.  No break-in required.  And I appreciate the modest price as well as the subdued colors....no garudy, fluorescent neon colors screaming &#34;hey, look at me&#34;.
