My friend told me repeatedly that I needed good shoes to walk in and I ignored her advice and carried on wearing my ballet flats on my walks up to my parents house. Let me tell you, that was a huge mistake that I soon regretted after several days when the soles of my feet were virtually bruised. I then bought a pair of Sketchers Go Walk on her recommendation.
Now to be frank, I don't think that they're the prettiest footwear ever but I was willing to comprise style for comfort and boy are they comfy! They're ridiculously lightweight considering that they're a full shoe. I love that my feet feel like they're gripping the floor with each step giving me far more stability.
I think you would be best to try a pair on before you buy as I don't think the sizes are too accurate however, I did find the best price to be on Amazon so it's worth bearing in mind.
Overall, I absolutely adore these shoes and would recommend them to anyone needing a good pair of true comfort as they work out.
