The toddler version (the box says Lil' Energy Lights) only had 2 colors around the outer half of each shoe instead of the full rainbow around the entire shoe. They also lacked the same number of functions as the kid version, and they don't appear to be chargeable? Or if they were, I couldn't figure out how. No instructions in the box. It would have been so cute to have the kid version for my 1.5-year-old, but they really didn't meet the benchmark. No warning on the differences in the toddler version meant I initially thought they were just broken. Disappointing.
