Britax B-Smart cosytoes/footmuff?

[Aloha31]

I have the B-Smart 3 and it doesn't come with the cosytoes...they are quite expensive. Are there any universal footmuffs which would do the same job (and last til 3 years)?

Thank you.

I LOVE my buggy snuggle. I paid more and got waterproof one. My daughter is nearly 2 and has loads of space.
