I bought these to use while doing water aerobics. My shoe size has been sz 10. These are soa large. I hope they shrink a wee bit as theyd probably feel & look better, so remember they run larger than actual size.  On left shoe, the liner was bent double, which i corrected, however I didnt glue it down, so I expect it to come out eventual,y, then I'll have to buy the proper shoe liner glue & fix it.
