Are they good grip? My kids love to run around outside.

The rubber soles are sturdy and flexible, they hold well and have good grip and support, effectively preventing baby from slipping and helping toddlers learn balance when their toes are on the ground.

Are they slip resistant?

Our soles are non-slip design, and there is a video about anti-slip test in the product introduction. You can buy with confidence!Anti-collision shoes to protect little feet from sharp objects.

I would like to buy for a 6-12 month what is the recommended size to get?

Hi Kelly, Thank you for your question. Usually, the foot length of a 6-12M old baby is between 4.5 and 4.7 inches,choose size 4 toddler. Since the length and width of each baby's foot are different, I suggest you measure the baby's foot length first. We recommend you choose a insole length that is about 0.2-0.4 inches longer than your baby's feet. If your baby's feet are thinner, we recommend you choose a insole length that is about 0.1-0.2 in longer than the baby's feet. If you don't know how to choose the size, please tell me the length of your cute baby's feet and I will recommend the size for you. Thank you! Jack
