My wife has these sneakers. She says they are true to size. The toe box is average to large sized - which works well for her. She has done lots of trail runs in the Tetons on the Arrow Trail, Crest Trail, and Grand Targhee Trails, etc...: she says these sneakers hold up in colder fall or wintery conditions (even without the Gortex) and have great sole stability and fabulous traction - even when climbing on wet or loose conditions. This is her third pair of Salomon sneakers; she wont go for anything else. She also gets alot of comments on the color - people love them!
