I am a size 9 women’s (US). Soft, flexible high grade leather. Ive ridden almost 900 miles of trails with this since February and its been perfect. Definitely would recommend these Its squishing my breasts so much, its uncomfortable. I dont slip around in these on the floor or in the shoes these are true to size measure from the inside not the soul bottom Yes i recommend Read reviews saying it collapsed. Now I have to go find some ink to print return slips and get this trash sent back. HOWEVER, order small like way small. Keens have hiking or work boot style soles.
