size matches US shoe size. I have wide feet too :)
These shoes are great for walking in streams and muddy water since they are light, comfortable, fit snuggly to your feet if you choose the right size, easy to walk with, and easy to clean afterwards. If you get them dirty all you have to do is rinse them with water when you get home! You don't have to wear socks and they are very low maintenance unlike traditional shoes. Make sure to look at the chart and buy according to the measurements of your feet and the suggestions given at the chart since that chart literally tells you the right size to wear.
