A few year back baby bogs boots were recommended to me on here for my DS. They were brilliantly warm, waterproof and flexible ( DS very early to walk and his feet got freezing in winter ) He had a few different sizes, some lasted better than others, now I have DD who's turned 1 years, but she needs a smaller size than I have. So needs a size UK 4. I just can't stretch to £40-£45 , so can anyone recommend something similar, but cheaper version or something in the same please? Ideally £20-£25 or free it's been a hard year.
