H&M are a brand I never really use on a personal level. If you ever wish to know the details of my own personal issues with their online transactions and my own issues with this then I will be happy to comment privately, seeing as it has nothing to do with the quality of their goods. So whilst I don't personally shop at H&M, it's hard to deny that for just £34 for a real leather high quality sandal is fantastic. Take them on holiday with you for the evening meal times and dress up a jersey LBD or shorts and tank with no real effort at all.
Plus if you don't love the green they are also available in black and nude (see below).

Beige Suede Slingbacks
I especially love the waffle effect upper - best seen on the green and beige. If you do want a pair of these, or indeed all three - please be fast as I don't think they will hang around for long at this price.
