I bought the Sole Platinum, Moszkito Archy, Orthaheel Ryder, and Spenco Polysorbs for a side-by-side comparison.

Moszkito Archy = 5 stars
PROS - the highest most pronounced arch, had adequate cushioning overall, was wide enough to provide full coverage for my wide feet, and looked rugged
CONS - leather means I couldn't take it to the beach or the pool

Sole Platinum = 3
PROS - made of rubber with an assortment of colors, which means you can wear it anywhere; adequate cushining; looked very durable
CONS - you could barely feel the arch and the straps were rough and scratchy (although not unbearable)

Orthaheel Ryder = 1
PROS - none
CONS - arch was spread across a very wide area of the foot, so I felt like my foot was tilted to the side...not comfortable at all! In addition, the sandal was too narrow

Spenco Polysorbs = 4
PROS - made of soft rubber that completely envelopes and molds to your foot. At $35, it also costs significantly less than any of the above brands.
CONS - Arch height was comparable to Sole's, but the material gave it an edge.

I kept both the Moszkito and Spenco - the former for daily wear, the latter for the beach and pool.
