If you can get your dog to stand still long enough to measure its paws with calipers, Finnish startup Bark & Sole has a treat for you: custom 3D printed dog shoes. These are engineered to fit each pup’s unique paw geometry (yes, even ankle circumference and dew claw placement), breed quirks, and gait mechanics, the company says. It's all about making sure Fido’s footwear doesn’t flop, twist, or fall off. Shoes range roughly from $40-$200 and ship worldwide.
