I had a pair of moccasins before this, but the sole was too flimsy and didnt give much support. Thats just about how they fit. I ordered a 7 M because it did not come in a wide. Last but not least, the sole is rubberized so you won’t be taking any tumbles on slippery floors. 69 full charges for the iPhone 5 out of one full charge of the Anker Astro E7 external battery. This oil is great.
