I cant say I understand his requirements, as Im generally easily satisfied. So far as being used to keep a "basic shoe shape", these XL shoe trees were able to fit in a size 11. I thought it might be missing spots, but after going over the same spot five times, the hair wasn?t getting any shorter. I wear them in the shower and while I?m getting ready after working out. Questo paio da altro venditore, però comunque non sono uguali i sandali. I don?t normally post negative reviews but here I go. I like that the metal "L" that goes over the door is covered with plastic, to avoid scraping off the paint. Couldnt be simpler to use. Me gusto mucho, quedan muy bien protegido definitivamente hize muy buena inversion?? So for starters, here is how I am using the bike rack.
