Put Some Spring In Your Step
The gladiator sandal has been around for a few seasons now, but the latest version has thinner straps than its chunkier predecessor, making it a sure fit for every foot. If you've been blessed with long, lean legs, the laces can rise as high as you dare; otherwise, go for a pair that ties around the ankle. "Gladiators add instant oomph to any outfit without being too trendy," says O creative director Adam Glassman. For the most flattering look, opt for shoes (including laces) in a shade that matches your skin tone.
