iSSi Thump pedals were a worthwhile improvement over my inexpensive Stolen Brand Thermalite pedals, on my older hybrid (I do use clipless on my road bikes, but prefer free-footing it on the hybrids for city rides).

The Stolen Thermalites are an outstanding value at around $15 for cycling that beats up pedals quickly. My set lasted almost three years of fairly sedate riding but a lot of miles. But after they were a bit loose I decided to try something a little better rather than try to rebuild the Thermalites. I'd already had a frustrating experience trying to rebuild some Wellgos and didn't want to waste time again.

The iSSi Thumps are also plastic but with a large, slightly concave footbed that really does hold shoes more securely. Just plastic pins, not metal. And supposedly rebuildable components. I've had 'em for over six months, no problems or complaints. They work great with everything from my heavy winter boots to lightweight deck shoes with thin flexible soles.
