Well I bought these and the Arch 2's. and I loved them both. After trying them both on in the house I kinda just sided with the arch's- http://www.amazon.com/gp/product/B0058XHC32/ref=cm_cr_ryp_prd_ttl_sol_6

had I not bought both intending to return one I would of been really happy with these. Bottle opener works great.

Side note, I plan on being on sail boats on my trips and I had concerns the bottle opener might mark up the boat. that was sort of the clincher to picking the Reef Men's Arch-2 the sole seems a bit more sneaker like and might have a little better grip while maneuvering on a boat.

other then that they are very nice.
