The Merrell Women's Terran 4 Backstrap is simple and unique - the easy-on and easy-off sandal that becomes a staple for everyday summer wear. The full-grain leather and 70% recycled textile upper combines genuine leather with sustainability-built-in construction, with a hook-and-loop closure system handling quick fit adjustability. 100% recycled webbing closes the upper, 60% recycled microfiber lining handles the inside-the-sandal climate, and a 60% recycled microfiber-wrapped insole delivers underfoot comfort. Cleansport NXT treatment handles natural odour control across long-term wear - meaningful in a sandal that's likely to see warm-weather use without socks. Underneath, the FloatMax Foam integrated insole delivers the soft, smooth underfoot experience the Terran is engineered around. A Super Rebound Compound midsole provides durable shock absorption to help reduce torque and ease the transition into the midfoot. The 30% recycled TPR outsole handles grip across mixed surfaces - sustainability built into the rubber compound, not just the upper. Around 205g per half pair - properly light for everyday summer wear.Merrell Size Chart (Women's Footwear)UKEURUSAJPN (cm)CHN (mm)537.5723.52355.5387.524240638.5824.52456.5398.525250740925.52507.540.59.5262608411026.5265Merrell use standard EU/UK/US sizing with CM (Japan) and MM (China) length references.Fit note: Merrell sandals run true to size.
