I think perhaps Id order the 9. 5 and these fit perfectly (women?s 7/men?s 6). With this charging base, you can simply pick up the speaker by its handle whenever you want to use it as a portable Bluetooth speaker in a different room or outside your home and then when done just return the speaker, disconnect your Bluetooth audio device and the Bose Portable Home Speaker automatically turns back into a full-time smart speaker again. the inserts have no support and my sole feels it3. The company posted a size chart, I would suggest measuring your foot before ordering to make sure the length is correct. It works great and very easy to install. As shown in the photo I ordered the the wine colored slippers, size 6. Save your money, I?m so annoyed that I?m going to have to buy another cord in such a short period of time and I only use the headphone s to play my instrument at night. During use the back support does wobble a little when the adjustable bar is in either of the 3 slot while lifting weights. After just 2 days, the inside seem at heel on right slipper split and I expect will continue.
