“I usually wear 10 1/2 to 11 depending on the brand, sometimes 10 if the manufacturer tends to make their shoes a little large. I ordered size 11 and it was so tight it was squishing my toes. I returned it and bought something else in a store.”
“These shoes are very light weight (featherlight) and appear to be very well made for the price. The look and design of the sole is excellent IMO. However, the right shoe (in both the US size 10 and 10-1/2) rubbed the top of my little toe. It was bad enough that I knew I couldn't walk any long distance without increasing pain and abrasion of the skin. You will need to try these on to see if you have the same issue. Maybe the toe box needs to be just a bit larger or they need to relocate an area of stitching on the top of this shoe. If it weren't for the rubbing I would love these. I ended up buying a pair of Merrell Men's All Out Blaze Sieve Water Shoes (here on Amazon) instead, which do not rub and I am very happy with. BTW, this Aleader Men's Mesh Slip On Water Shoe runs just a bit smaller than I expected. You might want to order your size and another pair one half size larger to ensure you get the fit you are looking for. Just return the pair that is not the right fit for you.”
