the size chart given is not correct. according to it my shoe size is 4, but no. 4 does nt fit in my feet. it's a bit small. so i have to exchange it with a bigger size, but there is no no. 5 in the color option i chose, so i have to change the shoe color also. all this wont happen if the size chart was correct, i could have chose the perfect shoe at once. otherwise the material is nice, it's light-weight and comfertable to wear.
