I always wear a 9-1/2 or 10 but I had to get a size smaller in this shoe for them to fit well. The sound quality is very bass, this microphones has a long cables so prepare for some cable management. Girlfriend Loves these the only reason I gave it 4 stars is for the straps being too lose I love the height of the heel and also the style. So very cute . They have wonderful sparkle and will go well with jeans or really anything blue. These are very useful, and surprisingly sturdy/stable, despite some questionable welds that I expect will give out over time. I’m very pleased and give their product and customer service a full 5 stars. The controller has a clean white look. 5 for other brands of shoes but 12 is the right size for these, so I guess these run slightly tight. Im pretty disappointed and may look for a replacement cable on their website as my daughter was super excited to use these.
