I ordered several Merrell sandals for my daughter who has high arches and needs adequate support. Had emailed the company in advance to see if the sandals provided good arch support since we've had luck with their shoes/boots in the past. Merrell told me yes, the arch support was as good as their regular shoes. Was very disappointed. Just a slight arch, but nothing near the support of their regular shoes. Nice sandal otherwise, but just not enough arch support for my daughter. Wish the sandals modeled their other shoes which have been fantastic for my 7 year old.
