Livie and Luca


Livie & Luca offer an array of different sole types within their range; each one is a slightly different length and fit. Here at Happy Little Soles we only stock the most barefoot soles so you can be sure you get the best options for your little ones.

The Trac Sole is nice and wide but not very flexible so is better for more confident walkers. The Honeycomb Sole is lovely and light and flexible and a good wide fit, although slightly narrower, but has the benefit of going up to US13. However it does have a little bit of stiffening in the heel so again preferred for more confident walkers. Please note that the newer styles on the honeycomb sole have an updated size structure and are consistent with the Jumper sole.

Each sole measures and fits a little differently so do check out the measurements below and the individual fitting notes for each shoe.
